You can now edit bookmarks (and recent) names...

WIP UILists for filebrowser: add access to three remaining types.

This also change update of active bookmark indices to happen in file_refresh().

Still not fully working, of course.

Merge branch 'master' into asset-experiments

WIP: merge work on local branch about using UILists for bookmarks, be able to rename them, etc.

Doing it mostly because I need some update work done here so far to get py uilists/bookmarks working.

This exposes/moves part of bookmark code to ED_ area, so that it becomes available from e.g. RNA.
And adds RNA struct and such to represent a bookmark entry.

Also, Bookmark format is ammended to store optional custom names.

All this is still *very* crappy, should probably take some time soon to cleanup the whole branch!

Add group preview generation too.

Fix stupid error (CMake install does not clean removed files it seems :/ )

Various improvements to obj preview generation:

* Do not render cameras, lamps etc. for now.
* Generate bbox in camera local space, gives much better results.
* Add an op to clear previews from files.

First basic pyscripts to generate previews for objects.

Much to be done still, but with it you can select some blender file,
and generate a basic rendered preview of each object.

Finalized working new 'fit in camera view' code.

Now for any object, we have an rna func to call with a set of (flatten :/)
coordinates, and we get back location this object should be to 'see'
all given points.

Would need more refinements, but will do for now.

Full WIP work to get better control regarding 'camera' aspect of objects.

First expose a method in Object RNA to get camera projection matrix (done).

Then, expose a method to get camera position (and scale for ortho) so that
it fits a given set of coordinates (still unfinished).

this among other things implied rewriting `BKE_camera_view_frame_fit_to_scene()`
underlying logic so that it uses `CameraParams` system, instead of `BKE_camera_view_frame()` one.

Fix stupid merge error.

Conflicts:
source/blender/blenloader/intern/writefile.c

RNA access to previews (image and icons).

Note since this gives python possibility to change those previews,
we add flags to PreviewImage to tag as user_defined.

TODO: replace all those shorts-used-as-bools by bitflags!

Merge branch 'master' into asset-experiments

Ensure previews are up to date when saving .blend file.

Previuosly, we would only write existing data - and big previews were
nearly never generated by default.

Now, if saving previews is enabled, `wm_file_write()` will ensure
all 'common' previewable datablocks do have up-to-date previews
(brushes remain TODO here for now, they have both a preview **and**
an icon_imbuf, sigh...).

This implied adding an 'immediate' non-job-background version of
`ED_preview_icon_job()`.

Note this does not include objects/groups/etc. It's not simple to generate
previews for those, will probably go for a user-launched py operator here...

Also, cleanup some debug prints!
