◆ GPU_is_safe_texture_size()

bool GPU_is_safe_texture_size	(	int	width,
		int	height )

Returns whether it should be "safe" to use texture of a given size.

The heuristic is that maybe allocating texture that is 25% of GPU_max_texture_size squared is fine. Note that the actual texture creation can still fail even if deemed "safe" by this function, depending on current memory usage, texture format, etc.
