For windows, NAN_NO_KETSJI was always set to false (as a result of
some strange merging). Unfortunately, Bullet doesn't build correctly
for gcc under cygwin (some private vs public stuff), so it is
important to be able to disable the game engine in these circumstances.

Orange: Added Alpha viewing option in Image window.

Tuesday merger of bf-blender into orange branch.

Orange: more work on float/exr buffers;

- EXR now saves and reads Zbuffers correctly
- EXR reading didn't set alpha to 1 yet when no alpha buffer was present

- ImageWindow: the "black point" only checked for the r value... now is OK
- ImageWindow: Curves panal has button "reset"
- ImageWindow: hold LMB drag shows rgba and z values. With SHIFT or CTRL it
applies black/white point whilte dragging too
- ImageWindow: saving file copied the entire buffer... removed that. Also
made the header print clear; this save only saves in own file type.

- Curves: zoom and drag now gets clamped by the Clipping value

- Imbuf: duplicate buffer only copied one quarter of to new buffer

Orange:
Accidentally didn't disable the tests I did for 'translucent raytrace',
a cheapskate SSS method;

http://www.blender.org/bf/rt.jpg
http://www.blender.org/bf/rt1.jpg

It slowed down render too much, was default on... but invisible! It needed
the F10 buttons "rt" to be huge (600-1000)

removed slow list handeling
faster vert comparisons
replaced spaces for tabs
removed unneeded getData() calls
general cleanup.

ifdef check for WITH_OPENEXR was removed from readimage for some reason
causing building without OPENEXR to fail. (Hopefully this doesn't mess up
current scons stuff, shouldn't but I haven't tested it after latest
changes in scons)

(I also cleaned up the Makefile a tad so it didn't check twice for WITH_OPENEXR)

*project file updates
- gets project files in line for compiling again

Added openflight import/export- Blight v1.2

Stupid old SConstruct made adding openexr more difficult than it should be.
Now OSX will always do openexr. Rewrite will address this bad implementation
once and for all.

MSVC compile error fix for subsurf UV.

Warning fixes for gcc 4 in iksolver and ghost.

Orange: tip from Nathan to get exr working in scons compiles...

Apply Subsurf to UV's.

This fixes most of the UV distortion issues with subsurf. Near seams
however there might still be some distortion, but this should at least
not be worse than before. Subsurf UV is enabled by default on new meshes,
and can be enabled in the modifier panel for existing ones.

Before and after:

http://users.pandora.be/blendix/smooth.png

applied patch from snailrose, related to multi-platform OpenGL extensions.

OpenEXR support for Windows Makefiles

Another msvc issue. Added #include <ctype.h> so it compiles.
See patch #3686

Fixed bug in convert function with Mesh objects.
Objects with no modifier could still be converted, but resulting meshes were corrupt and segfaulted Blender when cycling edit mode.
This tests each mesh object for modifiers before converting.

Resulting metaballs meshes were not visible in wireframe.

Also made the selection context nicer, All new converted objects are selected while objects that are converted are deselected.

added prototypes for bottom_sel_action and friends.
Steath Apprentice said its needed for MSC. Bug # 3687

Orange: and now for the real exr fun: float buffer support in Image window!

Image as loaded in Blender (from openexr.com):
http://www.blender.org/bf/exrcurve1.jpg

Image with different white point:
http://www.blender.org/bf/exrcurve2.jpg

Image with white and black point and a curve:
http://www.blender.org/bf/exrcurve3.jpg

Use SHIFT+click to set the black point, and CTRL+click for white point.
The buttons in the panel work too, of course.

The curves work after the black/white range was corrected, so you can
stick to curves with a normal 0-1 range.
There's also now a general color curve, marked with 'C' button.

Note; this currently only maps the float colors to a visible 8 bits per
channel rect. You can save it, but when the blender file loads the curve
or mapping is not executed until you click in the curves... have to look
at that still.
Speed for this is also quite unoptimized... still WIP, but fun!
