Summary: - Prefix all graphics subsystem names with gs_ or GS_ - Unsquish funciton names (for example _setfloat to _set_float) - Changed create functions to be more consistent with the rest of the API elsewhere. For exmaple, instead of gs_create_texture/gs_texture_destroy, it's now gs_texture_create/gs_texture_destroy - Renamed gs_stencil_op enum to gs_stencil_op_type From: To:
