Bug fix: Changing volume texture properties after render crashes (reported by mats on irc)
* Preview render copied the volume texture, but not the actual volumedata, so normal render and preview render clashed.

Fix for [#26516] Blender crashes for Particle Physics Path Editing.
* Silly own mistake from some previous code cleanup.

redo panel now runs check() function when defined, filesel and popup dialog were already doing this.

update x3d test md5s for recent changes, also ensure directory is created or export tests fail.

api function added for [#26481] Export to X3D of IndexedFaceSet should use X3D 's DEF USE mechanism

Object.is_modified(scene, 'PREVIEW') function for python exporters to check if any modifiers or shape keys are applied (weather the original mesh can be used for exporters).

Fix nan / black dots in image textures in some corner cases.

CMake, GCC: replace -Werror=strict-prototypes with -Wstrict-prototypes, some external headers cause this.

changes to icon loading
- look for icons in datafiles/icons (was looking in datafiles)
- was loading all images in datafiles/ on startup to check if they were the correct icon size, commented this since its unnecessary disk overhead on startup & images are checked for correctness when used anyway.
when running blender from the source dir would load splash.png every time.

also add missing NULL pointer check if the icon couldn't be loaded and ensure no buffer overflow check on icon path creation.

Small safety fix: clear temporary link list in node space when copying.

"Fix" #26445: edit mode vertex distortion

Discussed with Campbell, it's not actually bug and it's more about limitation
of topology mirror. It will work properly when both sides of mesh have matching
unique topology.
Added note to tooltip, so now unpredictable behaviour shouldn't confuse users
so much.
Also gray out "Topology mirror" when "X Mirror" is disabled.

fix for crash with textbox add poll function, missing NULL check.

fix [#26494] Auto run Python scripts option in User Preferences problem
- opening a file with blender by passing it as an argument would and loading it once in blender left script auto execute flag in a different state.
- command line args --enable/disable-autoexec were being overridden by the user prefs.

use defines for BKE_read_file, no functional change.

fix [#26507] Rename bone -> segfault

fix [#26504] Deselection of vertices not working in UVs editor

bugfix [#26505] zoom in selected keys on graph editor
measure uv vertex distance in screen pixels rather then image.

fix for building on some configurations.

workaround for problem compiling with glu 1.5.8 on windows

upgrade glew 1.5.1 --> 1.5.8, from the release logs changes are mainly for maintenance & supporting new opengl functions, this also fixes FreeBSD compile error.
