Bug 925 - Accept an ES3 Context, if reported via GL-Version-String w/o EGL_OPENGL_ES3_BIT_KHR
Add Quirk 'GLES3ViaEGLES2Config': ES3 Context is used via EGL_OPENGL_ES2_BIT and 'version 2' for create context attributes. - GLContextImpl.setGLFunctionAvailability(..)'s ES version validation only fails if requested major version == 1 and doesn't match. Hence requesting major==2 and having version 3 is tolerated. - GLContextImpl.setGLFunctionAvailability(..)'s Quirks: requested-major < has-major -> Adding GLES3ViaEGLES2Config - EGLDrawableFactory.mapAvailableEGLESConfig(..): Reflects has-major version, i.e. GLES3ViaEGLES2Config situation where an ES2 request leads to an ES3 version. Note: All workarounds can be found via lookup of GLES3ViaEGLES2Config (as usual when using quirks).
