This patch adds a new Media Type option to image format settings, which
is used in the Render Output panel, File Output node, and Image Saving
operation. The option does not provide any new functionality, but
improves the UX of selecting file types by categorizing the existing file
type option into:
- Image.
- Multi-Layer EXR.
- Video.
Each option would then list only the file types that fit that media
type. For Multi-Layer and Video, the file type option is no longer drawn
for now since only one option exist for now, OpenEXR Multi-Layer and
FFMPEG respectively. This also improves the experience by not listing
technical terms like FFMPEG in the UI, but rather use "Video" instead.
The original motivation for introducing this option is the recent
redesign of the File Output node. The problem is that the distinction
between images and multi-layers images is not at all clear, while the
behavior of the node changes quite a bit when multi-layer is chosen.
While now with the new option, the distinction is quite clear.
Implementation-wise, the new option is mostly a UI layer that controls
the available enum items for the file format and callbacks to set a
default format if the existing format doesn't match the media type.
However, core code is unaffected and still transparently reads the image
format only.
