glFinish — block until all GL execution is complete
void fsfuncglFinish( | void); |
glFinish does not return until the effects
of all previously called GL commands are complete. Such effects
include all changes to GL client and server state as well as all
changes to the frame buffer contents.
glFinish is NOT required before a call
to eglSwapBuffers
or glReadPixels.
glFinish can take some time and for
performance reasons it is best to use this function
infrequently and only when necessary.
