fix for bug where array buttons would use -1 index, causing an out-of-bounds check on an array.
added assert so this wont happen again.

add asserts for passing negative index values to RNA functions which don't support them.

Alternate fix for bug [#34369], where invalid polygon normals could be saved in the mesh data and in the file.

This was from initial BMesh merge, but should not have been added in since face normals are calculated and stored in the DerivedMesh.

Toggling editmode would remove poly-normals so its unlikely anything relies on this custom-data.

Woops! Fix for previous F-Curve path fix commit

Trying to rename a valid F-Curve would crash as no RNA property was set, but
*prop still had an uninitialised value.

code cleanup: quiet warnings for recent weight paint theme addition.

code cleanup: quiet float/double conversion warnings.

Bugfix [#32492] - Part 3: Error filter now includes drivers where there are
errors with the variables/targets, even if those errors are for variables which
aren't used (and are hence "harmless" errors)

This means that the filter can be truly useful for helping locate things that
need "cleaning up". For example, previously, there could still have been drivers
where there were some of these "harmless" errors would emit warnings, but would
otherwise appear perfectly functional.

The implementation here uses a slightly slower method of checking any errors in
these driver vars. However, it's no slower than what's done when these are
evaluated, and should be less error prone than introducing yet another type of
error tagging for this one case. The problem here is that the "driver invalid"
flag, which is usually set when a target has errors, gets cleared by the
pydrivers code if nothing went wrong when evaluating the expression. Removing
this clearing step will probably open a can of worms, so unless this method
proves to be far too slow, this simpler fix will do.

Experimental Feature: Ctrl-Click on the "name" of a broken F-Curve now allows
you to fix the RNA Path in-place

For F-Curves that are disabled or marked as having errors because their paths
are invalid (indicated with a red line underneath their names), it is now
possible to use the Ctrl-Click renaming functionality to bring up a textbox for
fixing the offending RNA Path "in place" (i.e. in the channels list) without
having to bring up the properties region first.

This makes it easier to fix the paths if you know what you're doing. However,
caution is still advised for most people. In particular, be aware that this uses
a separate "RNA Array Index" for indexing into array properties (i.e. location,
rotation, color) which will not be shown here, and can only be edited from the
panel (or datablocks editor/scripts).

Feature Request: "Show Errors" Filter for Anim Editors now works for
F-Curves/Animation as well as Drivers

This is useful for tracking down invalid F-Curves which might need to have their
paths fixed, or perhaps to remove F-Curves for controls which no longer exist in
a new rig.

Bugfix [#34519] deleted cache after duplicating an object with baked simulation

Weight Painting: Added userpref for zero_weight color.

Fix cursor display for anchored brushes due to own recent change of
paint coordinate system.

UI messages fix: no end point in tips! (from r55055).

code cleanup: also change BKE_blender.h BLENDER_VERSION_CHAR to 'a' so as not to confuse things.

Simple deform modifier: replace factor property by angle for twist and bend
modes, so we can show degrees rather than radians. Still refers to the same
DNA variable to keep backwards compatibility.

Patch #33807 by Gottfried Hofmann.

View All operator for motion tracking dopesheet.

Bug fix #34534

Fix for 2.66a

The new Copy/Paste objects feature could hang in eternal loop.
Only happens for objects that refer to another scene via linkage.

This fix then crashed Blender, needed to add a NULL check for screens.

Switch from DENSE_NORMAL_CHOLESKY to DENSE_QR

DENSE_QR is better behaved numerically and after recent
changes from Sameer there's no big difference in speed.

Update Ceres to 1.5RC3

It brings optimization of DENSE_QR and DENSE_SCHUR solvers.
