qzdoom/src/gl/system/gl_framebuffer.h
Christoph Oelckers 8e2ebe15fe - removed several unused variables from OpenGLFrameBuffer.
- removed the LastCamera logic in RenderView. This code predates the first GZDoom release and apparently was only added because back then R_SetupFrame was not fully compatible with the hardware renderer. Today it is not needed anymore.
