Linked object deletion

These objects contain data that are stored per context. We need to do some cleanup if they are used across context or if context is discarded.

Debug Groups

Useful for debugging through render-doc. This makes all the API calls grouped into "passes".

void debug_group_begin (const char *name, int index) override
void debug_group_end () override
bool debug_capture_begin (const char *title) override
void debug_capture_end () override
void * debug_capture_scope_create (const char *name) override
bool debug_capture_scope_begin (void *scope) override
void debug_capture_scope_end (void *scope) override
void debug_unbind_all_ubo () override
void debug_unbind_all_ssbo () override

Safe object deletion

GPU objects can be freed when the context is not bound. In this case we delay the deletion until the context is bound again.
