Various backend improvements are included in this commit, mostly for the benefit of exporting. These include: - Moving more non-GL code from OpenGL derivatives into base classes - An "export mode" that changes the cache behavior of video backends - Using the Viewer's UUID introduced a few commits ago - No longer hardcoding the pixel format/render mode in the backend (since they'll inevitably differ when exporting vs previewing) - Improved signalling for frames that are completed
