Remove code duplication.
Will look into nicely using uiStyleFontDraw later.

Enabled kerning for the default UI font for the places that are using UI_DrawString still and for filebrowser.
Makes text more readable :)

fix ford last commit - also remove file from CMakeLists.txt

removed unused code for image loading, was copied from 2.49 and never used.

Raised soft limit for cloud texture noise to 24 for easier access.

Removal of more ancient stuff. (Help url and some cygwin build file, which is not in use anymore)

remove BLI_bfile, has been in blenders source for quite some time but remains unused.
can add back in if its ready to be used ofcourse.

fix [#24554] Blender does not remember name of last saved picture
* image name is now set when the file is actually saved if it is empty. Otherwise it is only changed if we're not saving a copy.
* If previous image name is empty, filename will be 'untitled.png' for png saving.

NOTE: if we saved a copy of 'render.png' as render1.png, the save image dialog will be re-opened with the image name that Blender has (render.png) rather than render1.png.

Bugfix #24585

Quad view split 3D window: didn't work for "box lock" option when
using "view all" or "view selected".
Made it work nicely for animated 'smooth' view too.

Partial fix for NLA Channel-List Border Select. This part of the fix gets the selection ranges right. The next part of the fix (for tomorrow) will involve setting up access for NLA-Track properties...

Animation Editors: Channel Reordering

This commit restores the ability to reorder channels in the animation editors (DopeSheet/Action/etc., Graph/Drivers, NLA). The hotkeys for this are:
- Shift-PageUp = Move Up
- Shift-PageDown = Move Down

- Ctrl-Shift-PageUp = Move to Top of List
- Ctrl-Shift-PageDown = Move to Bottom of List

Do note that only animation data can get reordered using this.
So, do not expect to be able to change the object order (that is actually taken from the order that Blender actually evaluates them per update/frame).

---

In the process, I've fixed a couple of other bugs:
* Removed 'optimisation step' check in anim_filter.c for dopesheet with no filtering options modified, since this meant that the ANIMFILTER_ANIMDATA data filter was not getting processed (and potentially there were other maintenance problems with that).

* Made NLA Editor's channel list not totally duplicate the basic Animation Channels keymap. Instead, the "NLA Channels" keymap now only defines the parts that are different, and this then gets specified before the standard one so that these different parts will override the standard ones.

* Attempted to fix BorderSelect on NLA Channels list. Still not totally working correctly yet though.

* Moved "Euler Discontinuity" menu entry from "Channels" to "Keys". It really belongs in the latter, since it affects the keyframe values, rather than some aspect of the channel (i.e. ordering of channels or how they're displayed)

use RV3D_CAMOB define, theres no reason to use >= comparison either.
also fixed opengl render ortho test.

Inverted the opacity setting for Background Images through RNA.
I was testing with a patched blender where this wasn't a problem else I'd have noticed.

- avoid loop within loop for unique naming function (even though it wasnt likely to run often).
- off by 1 error with outliner naming length. was 1 too short.

de-duplicate unique naming logic, was used in 7 different places, convert into a function call.

bugfix [#24574] setting location gained from a matrix_world.copy().translation_part() (visual loc) after constraints causes NAN in object location after python script ends
shrinkwrap constraint was dividing by zero. also the shrinkwrap UI was incorrectly trying to draw a subtarget.

bugfix [#24575] On file save plus and minus don't re-evaluate whether a file exists
actually it was re-evaluated. just the flag was overwritten by the old button.

better exception check for calling operators. non dict/None values were being treated as None.

patch [#24576] aud.Handle.status return bool
from Dan Eicher (dna), no functional changes, just return bool rather then int types.

patch [#24577] MESH_OT_noise. Adds missing 2.4x noise vertex displace functionality.
from Dan Eicher (dna)

Also added a factor option so you can adjust the amount of noise applied.
