Subject: Add GLRendererQuirks; Fix shared EGL/ES resources;
Add GLRendererQuirks:
- Contains centralized 'tagged' workarounds for GL renderer bugs (quirks)
- Accessible via GLContext and GLDrawableFactory
- Initialized in GLContext.setAvailability*
-
Simplify GLGraphicsConfigurationUtil.fixOffscreenGLCapabilities(..) & use Quirks
- use quirks
- instead of passing booleans for each config, pass factory & device
Fix shared EGL/ES resources:
- GLProfile needs to initialize EGLDrawableFactory's shared resources before desktop,
so EGLDrawableFactory can use the fallback defaultDisplay & defaultSharedResource
for host mapped sharedResources (hack).
- If using defaultSharedResources for host mapped ones,
do not go through initialization cycles - simply map (sharedResource + context).
- EGLDrawableFactory: Use device's unique-key instead of connection only,
since the latter causes a collision (EGL-connection == X11-connection).
