Cycles / Tile Rendering:
* Added new option to chose the tile order.
In addition to the "Center" method, 4 new methods are available now, like Top -> Bottom and Right -> Left. 

Thanks to Sergey for code review and some tweaks!

* Fix for #31581. The issue was that we scaled the face prior to
projecting it. The original paper suggests to simply interpolate between
the two points of an edge if the distance of the point to that edge is
smaller than a threshold.

* Fixed both 3D and 2D code to utilize this. Possibly other places in
blender where this scaling is done will have to be adjusted.

* Changed vertex interpolation to use 2D interpolation, since it already
did projection on plane and 2d calculations are faster.

* Also added notifier on hard recalc when uvcalc_transfor_correction is
used. Results in instant feedback on UV editor when edge sliding.

comment fix.

Looks like no scaling is done elsewhere on blender for this code. I hope
this bug is squashed for good.

Motion Path drawing tweaks and fixes

* Green (current frame) color now extends to the segments on either side of the
current frame point. This is so that the path is more visible (especially on the
black/dark side), as those segments were prone to being interpolated such that
they became invisible

* Added padding for frame number strings so that they do not overlap the dots
anymore

* Fixed off-by-one error, which meant that the frame number for the first frame
step (white dot) didn't get shown

Bugfix #33803

(2.65a and older)

Case: ALT+CTRL+U (user prefs) made mousewheel change button values in inactive
window.

On opening 2nd window, or de-activating a window, the modifier
state was kept for that window. That meant that mouse-over in a window was using
the old modifier - for example for scrollwheel it would change values
in buttons.
