Implement client side PBOs for glReadPixel
Use PBOs in gl_helper
swizzle bytes on gpu
flip vertically on gpu
remove gl_helper_thread
Implements GLHelper::CropScaleReadbackAndCleanTexture() to be non-blocking in the client by using shared memory combined with a query (not requiring actual GL PBO support, which would not be available on Android).
