Bugfix #5515

Having splitted a screen almost into 128 subwindows gives crashes when you
try to make a 'full window'. Code was missing NULL pointer checks for when
new window failed to open...

Fixed crashes in the Action Editor when keys for shapekeys were displayed
and user tries to snap keyframes to frame(s) or mirror keyframes.

Modified the multires loading code so that it always checks for a NULL edge flag array.

added sharp edge theme color

== 'Smarter' Keyframing Bugfixes ==

'Smarter' keyframing tools ('needed' option for manual and auto keyframing)
now work better than before, with more cases handled in an predictable
manner. There are still a few cases it still doesn't handle well yet. Those will be
fixed in the next few days.

See comments in code for rules in place now. Also, I've changed the code
to use the IS_EQ macro instead of my clumsy sqrt((a-b)*(a-b)) calculations.

Sculptmode propset bugfix: texture angle should be ignored if there's no texture enabled.

Multires bugfix: when deleting lower levels, edge flags should be subdivided to the next level.

Added undo push for retopo all.

Another multires loading fix: if edge_flags is null, allocate a new array

Fix for a multires crash: when loading dverts, extra call needed to relink them.

Disabled interaction between multires and shape keys. Attempting to add a shape key on a multires mesh will give an error, and attempting to add multires to a mesh with shape keys will give the user an okee before deleting shape keys. (This isn't an optimal solution to the multires/shapekey situation, but a real fix is non-trivial.)

The combine HSVA node was missing, now all the color space seperators
and combiners are available.

== Compositor ==
* Added patch 5251 X/Y Offset to Split Viewer node, by Juho
(with some modifications from the patch version).

Also various small tweaks to compositor drawing & buttons.

improved z-locking (would previously still try to rotate about the view axis and then right it).
also added error messages for libdata and dont allow views with object locking to fly.

weightpaint_envelope_assign - was making an error checking a null vgroup
API_intro - changed URL from elysuin
others - added __copy__() docs.

== Armatures - Bone Paths ==

* Shuffled a few bone-path buttons in the Armature Visualisation panel.

* Added a new option for bone-paths drawing: Calculate/show the path
travelled by the 'head' (fat end) of bone. By default, this option is off.

* Also, I forgot to mention in last commit that I had added an option which
specified the time-difference between each highlighted point on the curve.

bugfix for #5552, please check this is as you expect (argunda)

Also added ease in/out for roll correction and a small lag for directional changes to motion shouldnt be jurky.

If people are serious about using this to record camera path IPOs then we should have a panel for motion settings (roll correction speed x and z and motion lag for eg.)

Corrected IThread.lib to IlmThread.lib.. thanks Stephane :)

Updating scons VC config to OpenEXR 1.4.0

Small change to keep MSVC happy -- defined variable at the start of a conditional block.
