Matthew Waters	608cf31a25	glshaderelement: implement on-demand create-shader signalling ... One may not have an GstGLContext available or current in the thread where one would need to update the shader. Support this by signalling create-shader whenever the one-shot 'update-shader' is set to TRUE.	2015-10-17 16:10:41 +11:00
