Fix related to #30152, rainbow colours produced when loading hdr image to 3D viewport/ the Nyan cat bug.

Issue is caused by scaling for power of 2 dimensions and mipmapping that happens through GLU. It looks like the library cannot handle float colour values above 1.0 correctly. Since we are close to release I will just clamp the srgb result for now even though it will result in a small performance loss for 16 bit textures only.

I tried a few things before that, glGenerateMipmaps + no scaling (supported for 2.0 GL hardware and up), or using our own scaling instead of glu among them which worked very nicely and gave a speedup too. However, since we are close to release and there may be issues with GPU mipmap generation, see:

http://www.gamedev.net/topic/495747-another-glgeneratemipmap-question/
(old discussion but better be sure than sorry)

I went for the most compatible solution. Maybe after release this can be tested if other devs agree.

Carve fixes and optimizations:

- Fixed memory lead in Carve_getIntersectedOperandMeshes
- Union manifolds only if they intersects second operand, leave manifolds
which doesn't intersect second operand as-is.

ffmpeg: don't use flags:loop for .h264, this allows to see the video in OSX quickview and Quicktimeplayer( windows ? )

Fix 30169: rotate edge needs more checking for bad cases

If you tried to rotate an edge that was part of a chain
between two faces, the join faces function would remove
the whole chain (else it would leave a 'spur') and then
rotate edge would crash looking for a vertex that is no
longer there.
Check for this case and disallow rotate if so.

Carve: improved handling of meshes with interesting manifolds

Unioning of intersecting manifold tried to perform as little union operations
as possible, but there were some not totally correct assumption which lead to
cases when unioning of manifolds of some mesh might be happened when one of
mesh sets already had got intersecting manifolds.

This commit corrects this incorrect behavior.

Discovered this when was looking into #30175: Boolean Difference causes 2.62 RC1 crash.

Fixing up some buggy cleanup code in BL_ShapeDeformer. This code was causing crashes and corrupting shape keys. This commit fixes the following bugs:

[#30059] Shape Keys is gone in Blender if you use Add Object Actuator in BGE
[#30024] Segmentation fault after addObject when using shape keys
[#28683] segfault in shapekey conversion code when running a game (YF, level home) twice

OSX: to make transition for mediaimports to ffmpeg reliable, ffmpeg_0.10 is mandatory

bring back stitchability indicator, this can work even now

Initial port of stitch operator for bmesh.

*operator now works with few limitations:

-still no preview(will be back soon)
-rotation will not work if only one uv is stitched between islands(will need method to calculate uv normal for manifold)

Also fixed island calculation for UvElements, fixes a crash when uv sculpting with "Sculpt all islands" turned off

Fix for [#30171] "Audio Muted" Does Not Mute Audio

Fix #30170: with file saved in texture painting mode, when going to object mode
the image texture is missing. The flag to indicate that the mipmap levels were
already loaded into GPU memory was incorrectly set then.

Fix #30155: crash with popup menu open while new .blend file is loaded,
CTX_wm_window is then set to NULL and checked in the event queue, but it
should be checked for removing handlers too.

use tabs for indentation

Fix quicktime export being broken in various ways: callback was missing
parameter, codec RNA wrapping was wrong, and there was a python script error.

OSX: let almost all animation imports handle by ffmpeg now, this is faster in many cases

Fix for [#27349] Sequencer: Meta Strips plays unavailable audio

Hopefully at least... Sequencer code is like <insert name of random ancient language that nobody knows anymore here>.

Fixed copy-paste of sound strips in sequencer.

Copy operator used to remove scene_sound from strips, but Paste operator didn't
restore which lead to total silence of newly added strips.

Code cleanup: add and use knife list utility functions

In preparation for code in progress that uses lists
allocated out of the knife arena. This also makes
existing code more readable and understandable IMO.

Also removed an #if'd out function that will not
ever be needed.

new bmesh tool - limited dissolve.

This is a kind of simplification/cleanup tool which joins adjacent faces and edges based on the angle.

I've written this as an exercise (since I havnt written a bmesh operator before), and because quite a few users were asking for the dissolve operator to be extended, but I think this kind of functionality needs its own operator.

access from specials menu and mesh menu.

notes
* this exposed a bug in angle_v3v3v3(). will merge fix into trunk after release.
* added utility function BM_vert_edge_angle(), to get the angle between 2 connecting edges of a vert.

Fix #30159: Boolean modifier creating non-concave faces

Issue was caused by merging triangles into quads policy which used to think
triangulation of non-planar/non-concave quads happens by 1-3 diagonal which
isn't actually correct in some OpenGL implementations.

Added check for non-concave faces when merging triangles. It will work fine if
original faces are flat. In case if original faces aren't flat this check might
fail and triangulate face when it's not actually needed or merge triangles in
a way which leads to OpenGL artifacts.
