ec792d2e9a infra: promote the GL engine to an official one. 
The ThorVG OpenGL/ES engine has been stabilized and improved
significantly. Now, as a graphics engine, its drawing features
are quite functional. It is time to officially release the
engine and maintain it in the release process.

Thanks @Ruiwen for going above and beyond!
