This adds basic authoring tool and author info ("Blender User" for now).
NOTE: Linux and OSX users need now to update their OpenCOLLADA libs - Blender should now compile fine with their latest revision.
Made some changes to the original patch to ensure linking is done correctly.
Some small cleanups for scons too.
- DocumentExporter changed due to function name change in API
- no more UTF lib
- enabled by default for win32
Note: debug libs will be added later, as well as 64bit windows libs.
For other platforms, get r746 of OpenCollada and build against that.
unrelated changes that ended up being more trouble to commit separate...
- removed BLI_split_dirfile(), was nasty, occasionaly modifying the source string, it could create directories and used the $CWD in some cases. was only used in 2 places in filesel.c, if this gives problems can address without bringing back this function.
renamed BLI_split_dirfile_basic --> BLI_split_dirfile
- view3d_operator_needs_opengl was being called for offscreen render when it wasnt needed.
rename BKE_get_image_export_path() to BKE_rebase_path() and take a filename arg rather then an image.
obj export file copy was also not working because of a missing import.
scons+vc build crashes on Blender start when BF_COLLADA is on, don't know why this happens.
Merging from trunk to get working vc project files, then will try to debug and locate the problem.
* scale and rotation of objects with negative scale is exported correctly. This is accomplished by:
** if ob has no parent, use ob->rot, ob->scale values directly
** if ob has a parent, a local matrix is computed without scale and rotation is derived from it, scale value is copied directly from ob->size
Noted a few other bugs:
* importer suffers from negative scale problem too
* bones with negative scale are exported incorrectly too
* object animation values are copied from FCurves which is not ok for child objects where values should be in parent-space
* added renamed files in revision 25337
* renamed BLI_util.h -> BLI_path_util.h for consistency
* cleanup of #includes: removed BLI_blenlib.h in favour of direct includes of the needed headerfiles in a few places.
* removed debug print in sequencer.c
* added missing include in blenkernel/blender.c -> bad dependency, needs to be fixed still
