BoxPack: remove unusable vertices while packing

avoids having to check placing boxes there.

BoxPack: add support for merging verts as they are packed in

Reduces the number of vertices to pack boxes into.

BoxPack: flag verts used in packed boxes

BoxPack: remove quad_flags array, replace with inline bit-shift

Box Pack: Improve when packing boxes of the same size

Smart UV Project: don't rotate islands which are almost square

Fix T39861: UI destroys float precision.

Note this is only a workaround in fact, adding some precision in radians case.
Validating the field will still generate a precision loss (doing otherwise is
doable-ish, but likely to backfire and/or add too much complexity in an already
complex area).

AutoSnap Bugfixes: NLA Frame/Second Step didn't work

Since the NLA was also using the standard transform mode by default, this meant that
no frame/second step-snapping was happening here (i.e. like for the Graph Editor).
The actual differences between doing true stepping vs nearest here are quite small
(and don't really make much sense with NLA Strips), so for now, it should be fine that
these are the same.

AutoSnap Bugfixes: NLA Editor - Nearest Second behaviour tweak

The previous behaviour for nearest second meant that transforming the strips often
caused their lengths to change (sometimes drastically), since strip lengths aren't
always uniformly x-seconds long. Now, it only snaps the start frame value, and adjusts
the end of the strip to follow.

This works well for most cases, apart from negatively scaling the strip, where it will
get "stuck" as a 0.001 frame long strip (and the viewport drawing will be a bit weird
during this time). Nevertheless, negative scaling of strips isn't something that's exactly
recommended.

AutoSnap Bugfixes: NLA Editor - Nearest Frame/Second

Split off handling for nearest second from nearest frame

More AutoSnap Bugfixes: Time Stepping in Graph Editor

* Frame Step now works correctly and as expected
* Second Step kindof works, but the handles are not well behaved.

Fix T39819: Decouple autosnap behaviour from time display

This commit cleans up and fixes some problems related to how the auto-snapping
behaviour in the animation editors works, resolving the issues mentioned in T39819.

1) "Nearest Frame" no longer snaps to the nearest second when time is displayed in seconds.
Instead, there is now also a "Nearest Second" option, so that either can be used
as needed instead of only when a certain time display is used.
2) A similar change has been made for "Time Step" - This is now "Frame Step" and "Second Step"
respectively.

Notes:
* Removed the unneeded getAnimEdit_DrawTime()
* Time Step/Frame Step don't work for Graph Editor yet (and seem to not have worked at all)
* NLA Editor also seems to be showing some weirdness now. Will be checked on.
* Cancelling nearest-second snapping doesn't work nicely, due to another bug with GraphEdit transforms.

Code Cleanup: short -> bool

Fix T39867: Hotkey is not displayed in the node editor's menu.

Making both keymap and menu values the same, and adding a (debug only) check in
IDP_EqualsProperties_ex() warning when comparing two floats with nearly the same value.

Follow-up to the previous fix for T37452: More descriptive tooltips for freestyles settings

Made additional tool tips revisions suggested by a comment to T37452.

Freestyle: minor UI improvements.

* The button icon for jumping to the Render Layers tab of the Properties context is
now RENDERLAYERS. Previous icon BUTS was too general.

* Thickness position options are grayed out if not applicable. These options are applied
only when plain chaining is used with the Same Object option enabled.

Fix T37452: More descriptive tooltips for freestyles settings.

Tool tips of some Freestyle parameters were revised so that parameter descriptions
are easier to understand for artists.

Quiet warning

Fix T39830: Viewer node update error in the compositor when using the seperate/combine YCbCr nodes

Mode of the YCC<->RGB was never set..

Fix T39785: Video Sequencer, Aspect Ratio issue

Sequencer preview was rendering all scenes with the context
resolution, which doesn't give proper result. Now made it so
sequencer scene preview uses scene's resolution.
