The old code trys to do a sscanf %s %d %s %d from a line in the
image file.
Now it copies over that line to a max buffer of size 540 chars before doing
the sscanf.
(I just picked a constant that was siginficatly large)
It also checks to see if it gets all 4 values if not return NULL.

working correct with translucency. Removed a check that presumably
is an optimization, but can't work correct and also gives no noticable
performance difference in my tests.
computers, probably due to slow multithreaded malloc. Now each render
thread keeps a list of qmc samplers that it fills as needed while
rendering (since it is hard to predict the actual amount needed in
advance due to ray recursion).
* Changed default UV wire drawing do be a grey line with a black outline, highlighting aroudn selected points.
* Moved some draw options out of the View menu into the View panel.
* Changed header buttons to make Vert/Face modes less confusing.
Transinfo transform event callback is not cleared once
a transform event is over, this casued handleEventBevel
to dereference a null pointer. Added a check for this,
but it seems the callbacks should be set to NULL when
transform loop is done?
act as if the object was in its original position, instead of being
different for all instances. However, this is desired behavior in
some cases and so breaks compatibility. Now it only does the new
behavior when enabling the "From Original" option.
kill the process. Some time ago SIGVTALRM was replaced with SIGALRM
to solve issues on linux, but this signal can kill the process on
solaris, so now it uses SIGVTALRM again there.
sprintf(str, "/bin/su root -c 'cd %s; /bin/tar cf - \"%s\" | (/bin/cd %s; /bin/tar xf -)'", from, file, to);
return system(str);
This would ask for a password in blenders terminal, in ubuntu there is no root user...
If this feature is added back it should be written in a much nicer way.
Also made HKey toggle hidden files in the file selector.
an upgrade to the new quicktime api to work, but that's not really
compatible with rendering out frames sequentially. For now it sets the
compression to minimum quality, which doesn't need seeking forward and
backwards.
For *nix sustems, recent physics pointcache refactor uses stdio.h's remove() rather then system("rm -f ...") for removing files, since it was a lot slower for removing pointcache.
Ton used the system command because there was some problem using remove() ~6years back, but he cant remember why, (maybe its not a problem now)
Simple error, remove wasn't returning a value, but keep an eye out for problems removing files, and if anyone can reproduce the "Unable to make version backup" problem when saving, we should look into it.
Also added a note about using # in the output path for blenders command line help text.

It just increases the max value for gamma correction to 10f. Which
as noted in the patch is the same as the Gimp's color level tool.

Before, A hash at the end of the string would be replaced by a number with 4 characters. This is still default if no #'s are in the string, so nothing has changed.
To use this function from the python api use scene.render.getFrameFilename()
=======================
Caching and Baking:
- The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates.
- There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles.
- The cloth autoprotect feature was removed.
- The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries.
- The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions.
- PointCache struct was added to DNA and is automatically allocated for each physics type.
- Soft body now supports Bake Editing just like cloth.
- Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now.
Library Linking:
- Added some more warnings to prevent editing settings on library linked objects.
- Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked.
- Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh).
Physics UI:
- Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth.
- Tweaked field panel buttons to not jump around when changing options.
- Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable.
- I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers.
- Fixed modifier error drawing glitch.
Particles:
- Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() ..
- Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading.
- Make particle threads work with autothreads.
Continue Physics:
- The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache.
- This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics.
Todo:
- Point cache can get out of sync with and undo and changing a file without saving it.
- Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion.
- Menu item and/or buttons for Ctrl+B.
- A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested.
- The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.
