Fixed an indexing problem with the regular mouse vertex select in weight paint.

It will draw vertices in wire mode.

update to match changes in trunk

manually make small changes to sync with trunk

manually copying changes from trunk, these were somehow missed in merged

Camera tracking integration
===========================

- Track preview widget is now resizeable.
- Marker position could now be adjusted from track
preview widget.

Bugfix #27927

This fixes assigning 'tweak' keymap option for border selecting in
Node editor. Thanks Perry Parks for the patch!

svn merge -r37793:37865 https://svn.blender.org/svnroot/bf-blender/trunk/blender

Merge info was /trunk/blender:36835-37793,37865-38157
so this should merge in missing files.

Camera tracking integration
===========================

Fixed bug with incorrect scale of UV project modifier
when Blender camera uses non-default sensor size.

script to report deprecated functions of text and their age in days.

fix [#28003] Unable to delete vgroup
still need to find how an invalid defgroup index is set, but at least dont show the vertex group as selected when its not.

fix [#27996] Smart UV Unwrap Still Results in Overlaps
real fix this time :S, I thought using old code from 2.4x would fix but quaternion needed to be inverted.

fix [#28005] Python Add-Ons are constantly reloaded if twice in the path
Addons are checked for their timestamps and reloaded when it changes but this failed when, 2 addons had the same name since different times caused 2 reloads on every redraw.

Now when duplicate addons are in the path now give a error message in the UI and print path conflict in the console and don't thrash reloading.

fix [#27971] Blender OBJ export with Z-Up setting produces an error and fails
changes to extensions coming up...

Bug fix: particle cache should only be cleared on the exact first integer frame, not in the case of a subframe between the first and second frame.

BGE Animations: Allow the Copy Transform constraint to work with external targets in the game engine.

Modified behavior when replacing input links: The new target socket for the existing link is now chosen from available sockets that match the _target_ type, instead of the source type. This leads to more usable replacements, e.g. for toggling inputs on mix nodes. Still not a great solution to the mute/autoconnect problem, but a bit more intuitive for replacements.

Material Animation export. (on going)

Changed the default keys for duplicate-nodes-while-keeping-input-links to ctrl+shift+dkey, to avoid conflicts with alt+dkey for linked duplicates.

Camera tracking integration
===========================

Click-and-slide behavior for placing marker.

Now "workflow" of adding new marker is following:
- Hit Ctrl+LMB
- Release Ctrl
- Slide mouse to give marker better position using
preview widged for this.

"Previous" behavior is valid still.
