Catchup with the tip

Merge 1. Pull in cpp files in the performance enhanced Khronos RI OVG files which are newly added. I've ignored platform-specific cpp files for linux, macosx, and null operating systems because this local solution has its own platform glue (i.e. facility to target Bitmaps but no full windowing support). I've ignored sfEGLInterface.cpp because this is used as a bridge to go from EGL to Nokia's Platsim which offers an EGL service. That's not relevant to this implementation because this is ARM side code, not Intel side. I just left a comment to sfEGLInterface.cpp in case we need to pick up this later on. The current code compiles on winscw. Prior to this fix, the code works on winscw, and can launch the SVG tiger (tiger.exe). That takes about 20 seconds to render. I hope to always be able to show this icon on each commit, and the plan is for the render time to reduce with this series of submissions. On this commit, the tiger renders ok in 20 seconds.

Changes to fix the TimeZone Server Crash

Changes to fix the TimeZone Server Crash

Get rid of un-needed float-specific defines around yuv support. Remove unintended support for rgb to yuv conversion. We only support yuv to rgb conversion.

Check if RIEGLDisplay is already created in CEglThreadSession::EglInitialize,then return EGL_TRUE

Minor updates.

Removed RDebug statements and added more error checkings.

Create EGL 1.4 implementation by merging eglrefimpl and EGL from sfopenvg Subject to some fixes in uiresources and uiaccelerator, this version removes the EGL 1 panics. A quick attempt to use the compositor renderstage wasn't successful, but not apparently due to EGL issues. There are a lot of RDebug::Printf statements still in this code, which will be removed in the next commit.

Make sure the syborg version of the openwfc adaptation is used
