@SYMTestCaseDesc
Check if EGL Implementation allows two processes to work in parallel.

@SYMTestActions
Run two processes that independently perform the same actions detailed below.
This test will check for the “VG_KHR_EGL_image” extension, if it is not
supported on this platform then the test will return immediately without failure.
Create and fully construct an RSgImage object
•	Set the iUsage bits to ESgUsageBitOpenVgImage
Pass the RSgImage object into eglCreateImageKHR() with
•	The target parameter set to EGL_NATIVE_PIXMAP_KHR
•	Use the current display and EGL_NO_CONTEXT
•	Use a NULL attr_list
Check that eglCreateImageKHR() does NOT return EGL_NO_IMAGE_KHR
Use vgCreateEGLImageTargetKHR() to construct a VGImage object from the EGLImage.
•	Check for errors (VGInvalidHandle is not returned)
Create a second RSgImage, and use it to create a pixmap surface that is
compatible as a target for the VGImage to be drawn to.
•	Set the iUsage bit to ESgUsageBitOpenVgSurface
•	Use the same pixel format as the RSgImage above.
Now that a eglContext and an OpenVG context have been created, use the
OpenVG API vgClearImage to clear to a chosen colour the VGImage previously
returned by eglCreateImageKHR.
Use OpenVG to draw the just drawn VGImage to the pixmap surface currently
linked to the context.
Call eglWaitClient() to finish the above drawing instructions synchronously.
Destroy the original image data
•	Pass the VGImage into vgDestroyImage()
•	Pass the EGLImage into eglDestroyImageKHR()
•	Close the first RSgImage
•	Check that the pixmap surface contains expected pixel values using
OpenVG APIs, vgReadPixels.
Close the second RSgImage and destroy the pixmap surface
Check for memory and handle leaks

@SYMTestExpectedResults
Pixmap surface has the expected contents in both processes (within tolerance)
No memory or handle leaks

Check when sharing SgImage between 2 processes where a writer process populates SgImage through VgImage and a reader process draws SgImage to window surface,
process2 has reference to SgImage even after process1 loses all references to SgImage

@SYMTestActions
Main Process: starts Process1 and Process2.
Process1: Creates an RsgImage and passes RsgImage ID to process2. Creates an egl context and a pixmap surface linked to it. Creates an EGLImage from the RsgImage previous mentioned. Creates a VGImage from the EGLImage.
Process2: Creates an RsgImage using RsgImage ID passed into it. Creates an egl context and a pixmap surface linked to it. Creates an EGLImage from the RsgImage previous mentioned. Creates a VGImage from the EGLImage.
Process2: Drawss the VGImage to the surface before Process1 changes the contents of the VGImage.
--------
Process1: Changes the contents of the VGImage
Process1: Closes the VGImage, the EGLImage, the RsgImage.
--------
Process2: Draws the VGImage to the surface after Process1 changes the contents of the VGImage and checks if the contents match the reference bitmap plus the changes made by the process1.
Process2: Closes the VGImage, the EGLImage, the RsgImage.

@SYMTestExpectedResults
No errors within both processes.
The content of the pixmap surface will match the one of the reference bitmap changed by the process1.
No memory or handle leaks.

To ensure that RSgImage with uploaded data can be shared across processes.
To ensure that reference counting of RSgImage works correctly.

@SYMTestActions
From the main process:
- Create M SgImage(s) with the flag ESgUsageBitOpenVgImage. The size are all the same.
  We are running through all the possible configurations, with the values assumed being:
•	EUidPixelFormatRGB_565
•	EUidPixelFormatXRGB_8888
•	EUidPixelFormatARGB_8888 (source only)
•	EUidPixelFormatARGB_8888_PRE
•	EUidPixelFormatA_8  (source only)
- Note that when using EUidPixelFormatA_8 as a source, the reference bitmap display mode used is EGray256,
  This is to enable using the reference bitmap as an alpha mask.
- Spawn N client processes. During the process launching, pass to each process single drawable ID from the SgImages.
  In order to define which SgImage needs to be passed to the particular process, there will be following
  formula applied: J = P Mod (M), where J is the sequence number of the image, P is the particular process number.
From processes 1 to N:
- Open SgImage by using TSgDrawableId, obtained from the SgImage which was passed from the process A.
- Using EGL extension, create EGLImage specifying as EGLClientBuffer SgImage which was created on
  previous step,  EGL_NATIVE_PIXMAP_KHR as a target and EGL_IMAGE_PRESERVED_KHR as an attribute
- Using VG extension, create VG image based on EGLImage from the previous step.
- Close Sg and EGL images
- Create second SgImage with the same size and pixel format as first SgImage and usage flag is set to ESgUsageBitOpenVgSurface.
- Create off-screen pixmap surface with underlining second SgImage and make it current for the drawing context.
- Draw VGImage to the off-screen surface (note that when using EUidPixelFormatA_8 as a source, the
  reference bitmap is used as an alpha mask).
- Draw VGImage to the off-screen surface.
- Retrieve surface data (see vgReadPixels() API)

@SYMTestExpectedResults
Creation of all drawable  resources have been completed without errors.
Image data obtained in client processes 1-N matches to the data which have been uploaded to the SgImages buffer from
process A. Reference counting works correctly and keeps VG image alive although bound Sg and EGL images have been destroyed.
When all resources are closed, resource count maintained by RSgDriver extension is zero in all processes.

/**
@SYMTestCaseID GRAPHICS-EGL-0415

@SYMTestPriority 1

@SYMPREQ PREQ2637

@SYMTestCaseDesc
To ensure that SgImage with the data rendered as Pixmap surface can be shared across processes.
To ensure that reference counting of SgImage works correctly

@SYMTestActions
From the main process:
- Create M SgImages with the flags ESgUsageBitOpenVgImage & ESgUsageBitOpenVgSurface. The size are all the same.
  We are running through all the possible target configurations, with the values assumed being:
•	EUidPixelFormatRGB_565
•	EUidPixelFormatXRGB_8888
•	EUidPixelFormatARGB_8888_PRE
- Choose egl config, supplying as a native pixmap type in attribute (flag EGL_MATCH_NATIVE_PIXMAP) the SgImages which
  were created on the previous step. The EGL_RENDERABLE_TYPE of the config attributes must include EGL_OPENVG_BIT.
- Create M pixmap surfaces based on SgImages from the first step. The surface is created with EGL_ALPHA_FORMAT_PRE
  flag supplied in attribute list if the underlining SgImage was of type ESgPixelFormatARGB_8888_PRE.
- In iteration from 1 to M perform three following steps:
	1. Make the pixmap surface current (see eglMakeCurrent(.) API)
	2. Draw something to the current surface, for instance, clear the whole area with color and then draw a
	   few graphics primitives. The drawing needs to be unique for each surface and complicated enough to
	   ensure that bit comparison will reveal any mismatch
	3. Make no surface current
- Close all pixmap surfaces
- Spawn N client processes. During the process launching, pass to each process single drawable ID from the SgImages.
  In order to define which SgImage(s) needs to be passed to the particular processes, there will be following
  formula applied: J = P Mod (M), where J is the sequence number of the image, P is the particular process number.
From processes 1 to N:
- Open SgImage by TSgDrawableId obtained from the SgImage which was passed from the process A.
- Using EGL extension, create EGLImage specifying as EGLClientBuffer SgImage which was opened on the previous
  step,  EGL_NATIVE_PIXMAP_KHR as a target and EGL_IMAGE_PRESERVED_KHR as an attribute
- Using VG extension, create VG image based on EGLImage from the previous step.
- Close both Sg and EGL images
- Create second SgImage with the same size and pixel format as first SgImage and usage flag is set to ESgUsageBitOpenVgSurface.
- Create off-screen pixmap surface with underlining second SgImage and make it current for the drawing context.
- Draw VGImage to the off-screen surface.
- Retrieve surface data (see vgReadPixels() API)

@SYMTestExpectedResults
Creation of all drawable resources has been completed without errors.
On return eglChooseConfig() must return EGL_OPENVG_BIT in config attribute list (actual attributes should
be retrieved via call to eglGetConfigAttrib()).
Image data obtained in client processes 1 - N matches to the pixmap surface which was drawn in the process A.
Reference counting works correctly and keep VG image alive although bound Sg and EGL images have been closed.
When all resources are closed, resource count maintained by RSgDriver extension is zero in all processes.

@SYMTestCaseDesc
Functional test - Killing the RSgImage creating process

@SYMTestPurpose
To verify correct operation of RSgImage sharing across processes when the creating process is killed

@SYMTestActions
Run two processes that independently perform the actions detailed below.
* From Process A
	Open the RSgDriver
	Create an RSgImage passing an initialised bitmap
	Signal (by semaphore or otherwise) to process B, passing the drawable ID to it

* From Process B:
	Open the RSgDriver
	Using the drawable ID, open the RSgImage
	Close the RSgImage
	Re-open the RSgImage

* From Process A:
	Unexpectedly terminate process A without performing any explicit clean-up

* From Process B:
	Wait for Process A to be killed:
	Create an EGLImage from the RSgImage
	Create a VGImage from the EGLImage
	Close the RSgImage
	Close the EGLImage
	Create an off-screen surface
	Draw VGImage to the off-screen surface
	Read the pixel data and verify that it matches the data populated by process A
	Destroy the off-screen surface
	Close the VGImage

@SYMTestPriority 1

@SYMPREQ 2637

@SYMTestCaseDesc
Functional test - Simultaneous reading and writing of simulated glyphs.
The rectangular area of RSgImage will be divided into the following section:
	 -----------
    ¦ 0 ¦ 1 ¦ 2 ¦
    ¦-----------
    ¦ 3 ¦ 4 ¦ 5 ¦
    ¦-----------
    ¦ 6 ¦ 7 ¦ 8 ¦
	 -----------
The image size is taken to be 90x90 so that it is easily split between 9 sub-sections
It is obvoious that each sub-section will therefore be of 30x30:

@SYMTestPurpose
To determine that the system can cope with simultaneous
reading and writing from/to area within RSgImage without corrupting each other.

@SYMTestActions
Run two processes that independently perform the actions detailed below.
* From Process A:
	Open the RSgDriver
	Create an RSgImages with no content
	For each RSgImage, create an EGLImage and from that create a VGImage
	Close the RSgImage and the EGLImage
* From Process B:
	Open the RSgDriver
	Open the RSgImage using the drawable ID passed from process A
	Create an EGLImage and then a VGImage
	Close the RSgImage and the EGLImage
	Wait for signal from process A

* Concurrently from Process A and the client process:
	Process A:
		For i = 1 to 9
			Shade section[i] to colour[i]
			Signal client process that section[i] can be read
			Repeat until client process signal read complete
				Shade sections surrounding section[i] to other colors e.g. when i=1, 
				surrounding sections are section 0, 2 and 4 
				End loop
			End loop

	Process B:
		For i = 1 to 9
			Wait for signal that section[i] is ready
			Create child VGImage for section[i]
			Read the value of child VGImage and compare it with colour[i]
			Signal process A to indicate read is complete
			Destroy child VGImage
			End loop

* Processes A and B:
Close the VGImage and RSgImage driver

@SYMTestExpectedResults
The content of each section read by client process should match the content written by Process A.
All image memory should be freed
