[ #5833 ] 2.43 RC2: Incorrect Bone rotation when 3D cursor set as Pivot

There's really ugly stuff going on with pose mode rotation in transform which I'll have to fix later, in the mean time, this commit fixes the problem (which happens when you rotate bones in post mode around an arbitrary point) and includes some juicy comments to further document the actual architectural problem.

Fixed accidental commit from yesterday.

Uncommit of previous working copy.

Fixed chroma key to use tanf instead of tan (float vs double). Fixed input/output checking to prevent running the node if nothing is connected. Drawnode.c in error. will fix in a second.

The Object restriction flag 'do not allow select' was only handled in the
end of the selection code. That gave bad errors, especially in solid
drawmode.

Instead, when an object is not selectable it is excluded from the opengl
selection code entirely now.

Bugfix for reading DXF files, custom data layer wasn't always
added properly.

Upward compatibility fix:

Redundant variables for postprocess gamma, multiply etc were removed.
Unfortunately that makes new saved .blend files initialize these vars
to 0.0, so renders come out black entirely.

Lets keep them in for at least 1 release cycle. Just 16 bytes per
scene :)

animation_trajectory - was printing deprecation warnings. cleaned up some of its code too.
Mesh - removing UV or Color layers didnt check if the active object was in vpaint of uv mode, removing the last layer could crash blender - now switch to object mode if its the last layer like the UI.

When converting a VAL buffer to RGBA the alpha is also set to the value in the VAL buffer. This should be set to 1.0f as in the other conversions or it results in an unevenly transparent buffer. Corrected to result in an opaque buffer.

BKE_node.h commit is in error, but harmless (oops).

== Action Editor ==

Added a few checks here and there to prevent crashes related to
no action being active.

This includes patch 5933 by Diego Borghetti (Plumiferos TD).

Scripts:
-Another update to the ac3d importer to handle models with wrong face data. Thanks Melchior Franz for reporting.

Bugfix #5919

Baking error: dupligrouped objects were not included in database for
bake. That should be, it can be used as shadow casters or AO casters.

added messages to scripts, stopping them from modifying multires meshes.
object_cookie_cutter - can now also use curves to cut holes in a mesh.

added missing reference in the docs for the edgesplit modifier
Extended the add object tooltip to note that new objects cant be on a visible layer.

fixed bug #5921, artifacts when image input used instead of zbuffer.

== Armature Buttons - ChildOf menu ==

This menu now respects armature-layers, so that it works better on
armatures with a lot of bones.

= python bugfix=

flareseed and haloseed minimums were off by one, thanks Carsten for the fix

Patch #5928 from Diego Borghetti (bdiego)

Blender crashed when selecting column-select options in Action Editor
if there was no action active at the time.
