===========================
- Initial implementaiton of new ID named MovieClip.
Currently it has plactically the same functionality as
images, but this functionality would be widen in nearest future.
- Initial implementation of SpaceClip.
This space is supposed to be used for acting with MovieClips
(opening, playbacking, math-moving interaction and so on).
Currently you could open image sequence/movie file here, pan/zoom,
use a playback here.
I've added cache visualizer to this space, but it's currently more
a developer's feature to see how cache system works, but it could
be adopted for further artists' usage (something like cache visuzlizer
for simulations).
- Added new theme area for Space Clip.
No special colors were defined here yet.
- Implementation of basic cache system for movies.
This cache system is very familiar with sequence cache system,
but it supposed to be more portable: at least cache keys aren't
limited with sequence-based data and current seqcache could
became an interface between sequencer and moviecache without
much logic (only logic related on keys handling would be necessary
here).
Implemented basic limitors (ab\mount of cached imbuf's), so it'll
be a bit more difficult to go out of memory when playing long
animations in Image Editor (this cache system could be used for
images too, in the future).
- Very basic tools implementation -- only sceletion added, no
real tool implemented (only camera focal length added to the UI
which hasn't got real affect on anything).
Assorted notes:
- Not sure about best behaviour for Unlink clip button: should
it be imageeditor-like (with de-referencing only) or text-editor
like (with removing datablock from file).
- Also not sure if tools/properties should be splitted into
different areas or it'll be better to have tools and settings
for this tool/item/etc in the same area (tools at the top,
properties are under them).
Code for properties area is '#if 0'-ed.
- Sound isn't supported during playback in movie clip.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
