Move bug fix hack so it acts only when it needs too.
It was showing "global axis" even when using MMB to access user defined orientation (with Ctrl).

Updated the "multiple library" fixing... it will now also pop up a
menu to warn user that the file needs a saveover to get the fix
permanent.

#3635

Vpaint/weight/texture/UV modes were disabling zbuffer draw after drawing
the active object, causing objects to be drawn after (only selected ones)
to have no zbuffer on.

Bugfix #3608

More bump issues... Env made very nice examples, but all of it quite nasty
to solve.
Three improvements I found nevertheless:

- bug in mipmap code for bump gave errors in one derivate, causing aliasing
- when Image texture option "Clip" was used, the imagetexture function
returned wrong value, causing the caller to create own normal based on
color (zero!).
- Mipmapped bump now also interpolates the samples (never did this...)

orange: cleaning up / (msvc) compile fixes to the new editnla functions (experimental / made for baking and AvailRot/Loc keying methods)

#3605

Shift+ctrl+A "Apply deformation" didn't work anymore, since we got the
Modifier stack. I've inserted a notice there for now, to point users to
the proper buttons.

#3598

Uninitialized 'alpha' flag in Image texture could cause render errors.
Didn't show in OSX though... (stupid system here inits stack to zero).
But, Ken Hughes found this, so all credits are for him!

Orange: Stupid darn branches maintenance is @#@$!
The fix in bf-blender to prevent the release to read groups got in Orange
branch now too... tsk tsk!

#3593

The user settings "auto rotate grid" or "auto scale grid" were never
implemented for new transform, apparently.

#3581

Using the MMB constraint chooser in Transform, accidentally printed the
setting from the orientation menu (Local, View, Normal).
Martin: not sure if this a solid fix... the print now looks fine, but the
code isn't nicer this way. :) (just a one liner change though!).

#3592

Normal rendering; adding gamma corrected halo could cause NaN's because
of a negative sqrt().

Orange: new icon image from andy :)

Orange; update commit on WIP project for Noodle editing. :)

- Grabbing works (Gkey) or tweak (LMB) or use RMB click-drag for grab
- Shift+d works
- Akey: select all
- Drawing links works too now!

Updated for new Mathutils (should be faster)
uses Mesh rather then NMesh
uses expernal box packer
uv coords are not stretched anynore.

Seperated out archimaps generic 2d boxpacking function.
For anyone who is interested in boxpacking the logic isnt
that complex and lscm could benifit from using it.

Archimap will use this rather then having the boxpacker inline.

orange: py2.3 compat

orange: bpy Pose type

Orange: Made dashed parent-offset lines option for drawing Poses.
Was too ugly! :)

Tri-Triple Subdivide filling was messed up. This should straigten it out when cuts > 2

added ICON_SORTBYEXT for sort by ext feature
.
