* Last minute commit, updating the view3d menus for the new
transform stuff. All transformation menu items are now in the
'Transform' sub-menu. Added To Sphere and Push/Pull, and items
like Shear, Warp, etc. have been moved to there from the
top-level Mesh/Curve/etc menus, since they are now available in
object mode too.

For texture fonts, the rasterpos has to be delivered as BIF_RasterPos().

This smells to me like temporal code... will study it. For now this
commit fixes error in header draw of fileselect.

Bug fix #2636

New AA font drawing (using texture) didn't get initialized on startup,
only when button was pressed. Confusing code... we need to remove all
#ifdefs here once.

#bug 2633

Keep fighting with proper normal calculus on extrudes... now the 'add grid'
had wrong normals again (alternating in rows).

Disabled GL_CULL_FACE in mesh drawing for vertex colors, weight paint.
This made faces hidden with normals pointing inside. Not nice for paint...

Some last minute tweaks, for world background image, 'Hori' must now be
enabled.
And when using Blender's AO parameters, the lowest sample number
when no cache is used is 4.

Oops, I've must had a weak moment... turntable is OFF again in the .B.blend
The trackball method is for real 3d work.... turntable for woossies! :)

Colorband didn't correctly compute with 2 entries being exactly on the
same spot. Was division by zero here... coded nice exception catching.

BTW: worked before june 2004... was part of commit for Ramp Shading.

Updated the .B.blend. Nothing radical, that's for the next release, when
tuho work gets merged.

- Manipulators on (already was though)
- Grid/floor size 60 parts (was 32)
- Audio window replaced with TimeLine, added TimeLine in Sequencer
- Editmode draw edge/faces option on
- Turntable view rotate (under protest! :)
- 2nd theme is the dark/orange theme by Andy
- added 5th screen for python (textwindow, script buttons)
- OSA, Ray on
- Render resol 800x600
- higher default octree level
- added outliner in Animation screen
- renamed default Cube to be "Cube" (not sphere)
- default lamp has 'ray' on.
- when you turn default lamp to shadowbuf-spot, clipstart is OK

It starts with the 'modeling' screen, single window.

Added some backward compatibility with old yafray blendershader. Because of missing
parameters the material preset menu won't be as useful. Both glass presets will look the same
because there is no 'filter' parameter in the old yafray for instance.
So using the new Blender version with an old yafray version should work a bit better,
though the other way around, using the new yafray with an old blender version, will generally
not work as well.

I added a few extra things. In 'yafray' panel re-arranged some buttons, and added a new
button 'Clamp RGB'. This button will be enabled by default and helps to improve AA on
high contrast edges in the image. When using bokeh however, it is best to switch this off,
otherwise lens shaped highlights will be quite a bit less visible.

Changed the 'extinction' parameter name to the probably more correct term 'absorption',
though mathematically it works out the same. Also changed the behaviour of this color,
it no longer specifies a color that will be removed as I wrote in the previous commit,
but instead the actual color at one (blender) unit of distance. The 'Ds' (distance scale)
button below the color sliders controls the scaling of this unit distance.
What this means is that if you take the standard blender cube, which covers two units of
distance by default, setting the distance scale button to 2.0 will make sure that the color
you specified is exactly that color at that distance (provided the base color itself is white
of course, or 'filter' is 0, otherwise it will be filtered by the base color too).
Beyond this distance the color will get darker.

The glow option for point/soft/sphere lights has a new parameter 'GloOfs', or glow offset.
Setting this to a higher value then 0 will soften the central peak of the glow.

Another unreported bug fix: For xml export, when yafray failed to render the xml file
for some unknown reason, or because of other problems, the export code would still load
the previously rendered image, this causes problems however if the image resolution is
not the same as the current Blender buffer, and so could cause memory corruption or crashes.
This is now taken into account.

World image backgrounds now use the blender mapping settings as well, but only the
'AngMap', 'Sphere' and 'Tube' settings. But in yafray those last two, unlike Blender, cover
the whole view, not just the upper half, so is not really fully compatible with yafray.
So now you have to set one of these buttons too when loading a hdr lightprobe image.
btw, something I forgot to mention in previous commits is that the exposure control using
the texture brightness slider is no longer restricted to integer values. It is now a
floating point value, so you're not restricted to the 0 1 and 2 slider positions anymore,
anything in between will work too.

And finally, display updating is now more like Blender, using the mouse cursor as frame
counter for animation, etc.

When backbuf doesn't exist, it crashed during render... Fixed!

On Render or Anim, no redraws should happin in the UI for sequence window.
This was enforced in a commit 5 months ago, for proper redraws while
working in sequencer itself (with scene strips)

Found by Ztonzy, explained by Jesterking. Thanks! :)

Bug fix #2629

Aye... OpenGL cannot draw concave (C shaped) polygons... that screws up the
Lasso tool, when it uses backbuffer selection.
Examined for little while the GLU Tesselation library, but apart from its
nightmarish structure, it's even stupid (no builtin clock/counterclock).

So, instead coded a DispList based function using Blender's edgefill.
Works like a charm! :)

BPython:
- Fix for bug #2621 reported by Yann Cointepas (material.setMode didn't accept integer param, only strings, making it inconsistent with material.getMode):
http://projects.blender.org/tracker/index.php?func=detail&aid=2621&group_id=9&atid=125
Applied patch #2626 by Ken Hughes to both Material.c and doc (Material.py):
http://projects.blender.org/tracker/index.php?func=detail&aid=2626&group_id=9&atid=127

- Small C doc strings update I forgot to add before, for Render slinks (reminder about Render slinks docs also by Ken).

Thanks both -- btw, Ken Hughes has contributed considerably improving bpy documentation and fixing bugs for this release.

Bug fix #2575

VertexPaint, FaceSelect draws with 'culled faces' but should therefor
check for negative scaling as well, set the glFrontFace() OK.

Bug fix #2627

For rendering wire a wrong offset was used to find vertices... was caused
by commit Apr 13, part of reconstructing Mesh and subsurf.

Disabled zblur render option when it was saved in testing builds. :)

Bug fix #2625

Darn #$%#$# code cleanup in NaN days screwed up recursive feature of
linking dynamically data among Blender files. It now only supported 1
'deep'.

Now you can link data from file1 via file2 into a file3, etc. Nasty code,
but supposed to work :)

Bug #2624

Typo in bspline interpolation code... a '1' should be '2', causing the
fourth key of interpolation always be equal to third.
Only shows error with larger key steps, like 5 frames or more. Nice it
was found before release!

updates and corrections for BPy Text3d module from Ken Hughes.
Thanks, Ken!
