* f-key for on surface brush now uses the same overlay for fixed mode so that the texture is consistent with the on surface brush
* tiled overlay now disappears when sculpting
* transparency of brush doubles when sculpting

* Fix: inverted the f-key overlay to match the other overlays

* Fix crash when hitting f-key
* quieted lots of warnings in wm_operators.c

=== Improvements to Brush Cursor ===

== Symmetry Dots ==
When the on-surface brush is enabled a dot now appears where each symmetrical dab will act
* Note: the normal brush does not have dots yet because they are not as nice to implement without a depth buffer

== Improvement of Fixed Texture Overlay ==
* The fixed overlay is improved so that it shows exactly which parts of the texture will be projected
* The fixed overlay disappears when sculpting so that it doesn't obscure the object

* Note: the tiled mode overlay does not disappear atm due to problems with its interaction with partial overdraw
* Note: wrap mode does not have an overlay at the moment due to the complication of implementing it
* Fix: turning tiled overlay off and on or adjusting the alpha didn't immediately take effect
* Fix: fixed texture overlay + rake had artifacts caused by bad clamping

* Fix: grab brush got foobar'd by a previous merge

Merge with trunk: 30741-30831
Mistakenly forgot to commit the merge before adding the following feature:
== Wrap Texture Mode ==
Texture map coordinates are local to the brush instead of projected from the screen.

nicholasbishop finished up his work fixing up brush icons

* was suggested I combine all the direction modes into a single enumeration by using RNA_def_property_enum_funcs

syntax error in rna_brush.c

* default object in startup.blend set to draw matcap as max mode

* spelling error, "substract"

* new factory defaults include Eclectiel's sculpt icons and new default brush settings for the new tools

* decrementing image_icon ref count from wrong place

* was converting the space factor for files subversion 5 from pixels to radius but some version 5 files are pixels and some are percentage so I'm gonna only touch even older files to be sure I do not convert any body's percentage setting that was already a percentage. This means that some settings as pixels won't get converted by I think thats ok.

* fixed crash when there is no active brush

* fixed crash when there is no active brush

* fixed crash when there is no active brush

* Reverting change to zoom in MatCap. I think the problem with artifacts on the edge must be either a bad MatCap or another problem and it shouldn't be covered up

* The area inside the MatCap texture is shrunk by 0.95 to help eliminate artifacts on the edges of object when using a MatCap
* Object Color is enabled in the MatCap material so that setting an objects color will tent the object that color. You can set an object's color in the Object panel on the right.
