Instead of having a separate CoglHandle for CoglClipStack the code is now expected to directly hold a pointer to the top entry on the stack. The empty stack is then the NULL pointer. This saves an allocation when we want to copy the stack because we can just take a reference on a stack entry. The idea is that this will make it possible to store the clip stack in the journal without any extra allocations. The _cogl_get_clip_stack and set functions now take a CoglClipStack pointer instead of a handle so it would no longer make sense to make them public. However I think the only reason we would have wanted that in the first place would be to save the clip state between switching FBOs and that is no longer necessary. |
