===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.

Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
Closed regions didn't always draw the (+) icon right place, confusing
for users.
Next to that, I think this icon is using a bad metaphor or visual language,
Illustrated best if you close a header in outliner or buttons. Icons are
UI widgets, for screen/editor layouts different controls can be stylized.
My preference is something that aligns visually to the seperators between
regions; for testing and hacking pleasure I've added two quick versions,
a small tabbish thing and a triangle. Enable these with debug menu,
ALT+CTRL+D, values 1 or 2.
This is simply drawn with opengl now. An image for it can be made as well.

There's other design ideas to explore as well, like making region deviders
8-10 pixels wide, with a 'drag me' dot on it or so. That takes some screen
estate though, and will require to add big editor-dividers too...
Fun stuff for the mockup-mafia to check on, we have time :)
- fix: user pref, window title was reset to 'Blender' on tab usage
- Undo history menu back:
- name "Undo History"
- hotkey alt+ctrl+z (alt+apple+z for mac)
- works like 2.4x, only for global undo, editmode and particle edit.
- Menu scroll
- for small windows or screens, popup menus now allow to display
all items, using internal scrolling
- works with a timer, scrolling 10 items per second when mouse
is over the top or bottom arrow
- if menu is too big to display, it now draws to top or bottom,
based on largest available space.
- also works for hotkey driven pop up menus.
- User pref "DPI" follows widget/layout size
- widgets & headers now become bigger and smaller, to match
'dpi' font sizes. Works well to match UI to monitor size.
- note that icons can get fuzzy, we need better mipmaps for it
If greasepencil became active, making Blender area full or restore
screen from full, the greasepencil handler was still running, using
outdated area pointer. This crashed Blender.
Now greasepencil modal() ends on the case its own stored area does
not exist anymore.
Hanging Tooltips solved!
It appeared to be that an active button remained in that state when
another region/editor became active. It then kept the button-activate
state, and therefore also the optional tooltip.
This only happened on fast moves, when a mousemove event was not passed
on anymore to the previously active subwindow.
It has been solved with a new notifier (SWINACTIVE), which gets sent on
new active regions. The screen listener then calls uiFreeActiveButtons()
to find out if buttons were still active somewhere else.
Right Mouse on area edges has menu to Split or Join. Works like 2.4.
Code needed cleanup and upgrade; operators were hardcoded tied to using
the area corner widgets only. In theory this is getting py ready even,
but that might need some additional testing. :)
Migrating "redraws" settings from TimeLine view data to per Screen.
The options are now still shown in the TimeLine "Playback" menu
though.
This means that whatever redraw settings you set in a TimeLine editor
will be used throughout a screen (i.e. editor layout) to determine
which editors will get updated during playback, instead of only
certain editors doing certain things at vague times.
---
Also, I moved some version patches pre 2.56 version bump into a
version-check for 2.56. These must've been missed when doing the
release...
Area split error: if the first split position was exactly aligned
with another 'edge' it merged the edges, causing the subdivision
layout to go haywire. Only happens in rare occasions, good find
this report :)
Issue: in user preferences window, using file selecting caused the
the userpref window to be saved, and not closing.
Reason: design error (by me) in using screen->full tag for denoting
a temporarily screen (like file window). Fixed by using a new
screen->temp variable for it.
System remained unstable though, noticed another issue with freeing
temp screens in wrong places. Seems nice stable now! Will check on
the wiki for relarted issues now.
screen verts were being rounded so resizing a window would end up moving the border in one direction.
for this to work properly we should store floats internally but for now compensate for this.
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.
Submitted by Shane Ambler.
The original patches made an enum for action zone edges, changed positioning for minimised icons and repositioned minimised icon for operator properties panel.
I kept the enum idea, but further improved on the naming. Some switches used in place of if/else blocks and added some comments. See patch tracker for more comments.
Patch by Alexander Kuznetsov
Reported by Chidozie Oku
From patch description:
"
Handler is now released on every exit from File Selector. For example pressing ctrl-up and then changing editor type
to another also releases the handler.
When an area is changed from SPACE_FILE, ED_fileselect_exit is called for clean up. It takes function of freeing folder
list and files (before it was done in cancel or exec functions) because they must be released on every exit anyway.
op!=null means cancel or exec was not executed so a handler was not released. ED_fileselect_exit then releases the handler
without changing screens.
"
Thanks!
Playback Jog Keys:
ALT+LEFTARROW: play backward (hit again for double speed)
ALT+RIGHTARROW: play fordward (hit again for double speed)
ALT+DOWNARROW: start/stop animation
This started off doing pointcache debugging but it's also very useful for users too.
Previously it was very hard to see the state of the system when you're working caches
such as physics point cache - is it baked? which frames are cached? is it out of date?
Now, for better feedback, cached frames are drawn for the active object at the bottom
of the timeline - a semitransparent area shows the entire cache extents, and more
solid blocks on top show the frames that are cached. Darker versions indicate it's
using a disk cache.
It can be disabled in general in the timeline View -> Caches menu, or by each individual
system that can be shown.
There's still a bit to do on this, behaviour needs to be clarified still eg. deciding what
shows when it's out of date, or when it's been played back but not cached, etc. etc.
Part of this is due to a lack of definition in the point cache system itself, so we should
try and clean up/clarify this behaviour and what it means to users, at the same time.
Also would be interested in extending this to other caches such as fluid cache,
sequencer memory cache etc. in the future, too.
