Bugfix for regression from 2.46 on cloth collisions reported by Daniel Salazar via IRC

Bugfix on IRC report. Luckily Daniel Salazar *does* carefully check our
regression files, it showed small dark outline errors on envmap.

This commit rewinds bugfix #8437, which actually had to be fixed on
another location in code, which was done a few weeks ago. :)

Bugreport in IRC: Area lamp, "Constant jitterred" had wrong alignment
code, causing the "SamplesY" button to overlap others.

Bugfix #17830

Index OB pass didn't support FSA for Ztransp.
Also made buttons to set black/white for non-RGBA images hide in Image Window,
the Curves color code only supports 4 channels atm.

Action Editor - Grease Pencil Bugfix:

When Action Editor was maximised, Grease Pencil data disappeared. This was due to the screen-swapping that went on. Now, it uses the old-screen that was stored in the maximised Action Editor's screen (should be safe...)

Grease Pencil Bugfixes:
* Onion-skinning with GStep > 0 was not showing enough of a noticable difference between ghosts. Improved method of calculating this.

* Clicking in a Grease-Pencil datablock channel in the Action Editor would crash

bugfix: copy/paste bug merged from Bullet main repo into Blender, hope it still can make 2.48

Embed point looks at last point, whether it was part of a continuous stroke or not (gives better results for poly lines)

Stroke selection (LMB and Shift-LMB).
Selected strokes drawn in red.
Eventually convert and delete will work on selection.

Skeleton Sketching

- Delete Sketch button
- During continuous strokes, when moving out from and back into an embeding, interpolate depth of the stroke like is done when snapping

Part two of the 2.48 release preparation!
(After this svn tag)

Part one of the release 2.48 commit.

* Added support for solid objects casting shadows within a volume.

Currently it only supports solid shadows - if it's a solid object, it will cast
100% shadow. Support for transparent shadows can potentially be added down the
track.

* Raytraced shadow casting for volumes

This is a first version and still has a couple of things undefined or
unimplemented, such as external objects casting shadows on or within volumes,
however volume->solid shadows are going ok.

As with other transparent raytraced shadows in Blender ,in order to make it work,
you must enable 'TraShad' on the material *receiving* the shadow. It would be
nice to make this a bit easier to use, since there's not much chance you want a
volume material to be casting solid shadows, but that's a bigger issue in the
renderer outside this scope.

The volume shadows are working from the same physical basis of absorption, and
support coloured absorption:

They also work properly with multi-sampled (i.e. QMC) soft shadows:

And by popular request the test file:

missing calls to countall() on switching scenes in the outliner.

* New option for step size: Randomized

This is on by default, and trades random noise for banding. It jitters
the step size from 75% to 125% of its original amount, and since it
uses the threaded random seeds, shouldn't flicker during animation.

These two images took roughly the same time to render:

* A few volume rendering tweaks:

- modified point density so that it returns a more consistent
density with regards to search radius. Previously larger radii
would give much higher density but this is equalised out now.

- Added a new volume material option 'density scale'. This is an
overall scale multiplier for density, allowing you to (for
example) crank down the density to a more desirable range if
you're working at a large physical scale. Volume rendering is
fundamentally scale dependant so this lets you correct to get the
right visual result.

- Also tweaked a few constants, old files won't render exactly
the same, just minor things though.

Added a -noglsl option to disable GLSL from the command line.

Multiply by armature inverse matrix to make sure converted bones are where they should be.

First draft for converting sketches to armature.

- New Convert button in the bone sketching float panel
- Only adds straight bones between exact points (not continuous strokes) for now.

hard limit in for bpy material was wrong
