goldberg_emulator/overlay_experimental/OpenGL_Hook.h
Nemirtingas dd530e80b1 Now passing to hooks device object.
Added Base_Hook::get_lib_name to track what renderer is hooked for overlay.
Objects used to detect renderer type are now also used to hook the rendering functions. So we don't have to build another device.
Updated VTables for DX12.
