Environmental settings:
•   Image Size: w50 h50
•   Simulated Load: 0%
•   Pixel format ESgPixelFormatARGB_8888_PRE
•   Number of benchmark iteration: N

The method of creation of the RSgImage is similar to the case taken from GRAPHICS-EGL-RSGIMAGE_LITE-0406

From Process A:
Open the RSgDriver
Create an RSgImage
Spawn a client process B, passing in the drawable ID of the RSgImage
Wait for process B to exit

From process B:
Open RSgDriver
For i = 0 to N
    Start timer
    Open RSgImage[i]
    Stop timer and record time

    Start timer
    Create an EGLImage[i] from the RSgImage[i]
    Stop timer and record time

    Start timer
    Create a VGImage[i] from the EGLImage[i]
    Stop timer and record time

    Record total time of RSgImage[i] open and EGLImage[i] and VGImage[i] creation
End loop
Record average opening time of RSgImage, and average creation time of EGLImage, 
VGImage and the whole RSgImage-EGLImage-VGImage chain
For i = N to 0
    Start timer
    Close VGImage[i]
    Stop timer and record time

    Start timer
    Close EGLImage[i]
    Stop timer and record time

    Start timer
    Close RSgImage[i]
    Stop timer and record time

    Record total time for closing VGImage[i], EGLImage[i] and RSgImage[i]
End loop
Record average closing time of RSgImage, EGLImage, VGImage, and the whole VGImage-EGLImage-RSgImage chain

Close RSgDriver
Exit

@SYMTestExpectedResults
    The creation/opening of RSgImage, EGLImage and VGImage must return no error. 
    The average time shall be made available in an easy-to-use format

@SYMTestPriority 1

@SYMTestCaseDesc
    Performance test - Drawing of VGImage

@SYMTestPurpose             
Compare the relative speed of drawing a regular pre-existing VGImage with the 
speed of mapping in a VGImage (starting with a drawable id) and then drawing that.

@SYMTestActions
Environmental settings:
•   Image Size: w50 h50
•   Simulated Load: 0%
•   Pixel format ESgPixelFormatARGB_8888_PRE
•   Number of benchmark iteration: N (may vary depending on hardware capacity)

From the main test process:
Spawn two processes A and B
From process A:
Open RSgDriver
Construct TSgImageInfo object with
•   Size: 50x50
•   PixelFormat: ESgPixelFormatARGB_8888_PRE
•   Usage: ESgUsageBitOpenVgImage;

Creation of the RSgImages:
For i = 0 to N
      Form pixel data in such way that there will be a mixture of opaque and transparent pixels.     
      At least one coordinate of the opaque pixel will be unique for any iteration.
      Creating RSgImage with initialized data, size: 50x50 and format:  VG_sARGB_8888_PRE. 
      Send RSgImage drawableID to process B
End loop
Close all RSgImages after they will have been opened in process B
Close RSgDriver after process B finishes with benchmark measurement.

From process B:

For i = 0 to N
     Receive and store drawableID[i] from process A
End loop

Init EGL, create context and pixmap surface. Make the surface current.
Creating regular VGImage:
For i = 0 to N
    Create VGImage[i] with size: 50x50 and format:  VG_sARGB_8888_PRE
    SetSubData for VGImage[i] with the same data which were supplied on RSgImage creation
End loop

Draw regular VGImage:
For j = 0 to 4
    Start timer
    For i = N to 0
        Draw VGImage[i]
    End loop i
    Stop timer and record time
End loop j
Complete all outstanding requests on the current context (vgFinish)
Record max, min, average drawing time of VGImage
Check that deviation between max and min time doesn’t exceed 5% (max – min / mean) < 0.05

Destroy all regular VGImages

Open RSgDriver
Mapping in VGImage from initialized RSgImage and perform drawing:
For j = 0 to 4
    Start timer
    For i = N to 0
        Open RSgImage[i] with drawableID[i]
        Create an EGLImage[i] from the RSgImage[i]
        Create a VGImage[i] from the EGLImage[i]
        Draw VGImage[i]
    End loop i
    Complete all outstanding requests on the current context (vgFinish)
    Stop timer and record time
End loop j
Record max, min, average mapping and drawing time of VGImage
Check that deviation between max and min time doesn’t exceed 5% (max – min / mean) < 0.05

Destroy context, surface
Close all VGImages, EGLImages and RSgImages
Terminate Egl environment
Close RSgDriver

@SYMTestExpectedResults
The creation of RSgImage, EGLImage and VGImage must return no error. 
The drawing speed of regular VGImage and mapping VGImage (starting from drawable id) 
with following draw is made available in an easy-to-use format for further analysis and 
comparison.
