ensure framebuffer textures are detached and deleted, avoid leaving framebuffers bound when not needed * render: avoid calling glDeleteProgram on no program its safe to do so but it adds a bunch of unnecessery lines in apitrace when tracing. if guard it and return early. * opengl: ensure texture and buffers are unbound ensure bound buffers are unbound after use, also detach textures from framebuffer before deleting it otherwise it will become dangling and essentially leak.
