Bugfix;

- buttons "Show" and "Key" didn't set the active constraint, causing
confusement in display for the IpoWindow

Also made the backdrop for constraints and modifiers to use the Panel
theme color, making it better integrated.

Removed ancient (2.1) feature for Constraints... a highly undocumented and
unpredictable one!

This is what it did; if two or more Constraints are of the same type, it
accumulates the Target positions/rotations for the constraints, averages
them, and then only applies the last Constraint in the row. It seems to
be a trick to blend IK Constraints or so... in all other cases I cannot
find a good use for it (nor did Bassam).

For example; add three Empties, and make one Empty to have 2 location
constraints to the other two. This just didn't work, unless you insert
an "Empty" constraint inbetween.
I will post in the blender.org animation forum feedback for it too. :)

Its quite easy to make it an option, but I first like to grasp fully what
the actual use of such an option is.

Suppressed another GL_FRONT drawing routine, causing potential slowdowns
for some configs. This was an old hack for sgi's, so I've put it behind an
ifdef for sgi and suns now.

Test if blender still works by switching screens, and check for the borders
between the blender area windows. These should draw all nice empty/black.

Fix forward declaration of drawscreen()

Division by zero prevented in new hair strand algo. It showed as vertical
lines, especially with the "Step" size low.

Recommitted this commit yesterday, was apparently done in the wrong
directory... so the slowdown was still evident!

Maintenance commit;

- *Giant* speedup for LMB frame-dragging in ipo/action/nla windows. It was
calling a routine that accessed frontbuffer drawing.... a very old patch
for SGIs even! :)
- Prepared code for support of unlimited Shape keys
- Curve objects didnt draw correct for selection-outline option

Hair!

Thanks to testing in studio orange (thnx andy, matt!) I've found the
simple way to code it.

Static particle systems, when not set to wire or halo, now render 1 pixel
wide 'strands', which are actually just faces with vertexnormals and
proper orco texture. Check for quick fun;

(and rt6, rt7, rt8)

set object->recalc flag when we change object's loc, rot, etc.
fix for problems with frame change scene scriptlinks.

Shaded drawmode, ogl preview render, does update for lights.

-fix for angleBetweenVecs
* adds a test to check for zero-length vectors

Refcount fixes
* fixes posible reference count issues with mathutils
* mathutils classes should no longer memory leak

- tooltip fix, double sided pretended it was per face

added the method saveRenderedImage to the RenderData object
- should allow users to render a filename.extension to the render path
Example:

import Blender

s = Blender.Scene.GetCurrent()
r = s.getRenderingContext()
r.setRenderPath('C:\')
r.render()
r.saveRenderedImage('myRender.jpg')
Blender.Scene.Render.CloseRenderWindow()

drawscreen is called before it's defined crashing msvc

- added some equivalency testing for vector classes
>, >=, <, <= test vector magnitude
==, != test vector values 'within epsilon' :)
- inspired by ideasman

Ftgl patch for texture fonts got lost... somehow. That made them much
slower than pixmap fonts. Test on buttons window CTRL+ALT+T timer shows it
goes down from 2500 to 100 on this commit. :)

Action editor: drag with LMB did three redraws... causing slowdown. Bug
since 2.0 it seems.
