Functions
int	is_glx_extension_supported (Display dpy, const char query)
	// ripped off from glxgears.c Determine whether or not a GLX extension is supported.


int	readbytes (const char fname, char &buffer)

int	readyuvbytes (const char fname, GLubyte &Y, GLubyte &U, GLubyte &V)
	Auxiliary routine for testing.

void	zeroyuvbytes (int ysize, GLubyte &Y, GLubyte &U, GLubyte *&V)
	Auxiliary routine for testing.

void	getPBO (GLuint &index, GLsizei size, GLubyte *&payload)
	Get PBO from the GPU. There are two versions of this function: other one can be enabled in source for valgrind debugging.

void	releasePBO (GLuint index, GLubyte payload)

void	getTEX (GLuint &index, GLint internal_format, GLint format, GLsizei w, GLsizei h)
	Get texture from the GPU.
