* Bug Fix: briefly broke anchored strokes

* made random/rake into a drop down menu

== Symmetry Feather ==

Symmetry feather reduces the strength of the brush if it overlaps with other symmetrical instances of the brush. Works in mirror and radial modes.

Rearranged UI because symmetry seems to have enough options to deserve its own panel now.

Made 'lock axis' into a set of toggle buttons so if takes up less space.

* removed some debug traces I left in

* default overlay color changed to black
* can change overlay color from user prefs
* bug fix: unified strength wasn't showing in user prefs

* i can see creative uses for random rotation and drag dot
* however, random rotation and rake are mutually exclusive

* bug fix: rake would jump when it was around 360==0 degrees
* also, changed method of smoothing rake to be more like smooth stroke
** may expose variables for smoothing rake later

fixed DNA and blenderplayer compiling

* bug fix: overlay wasn't recalculating when you zoomed it back out
* tweak: changed some < to <= so that the edge is included
* made minimum texture size for overlay 256x256

* bug fix: fkey resizing wasn't taking into consideration unified size and strength

* only sculpt mode should use the unified size to draw the cursor for now

* enabled roll out icon menu for other paint modes

* quieted some warnings in sculpt.c and paint_stroke.c

== Unified Size and Strength Option ==

Under brush options can choose to use the same strength and/or the same brush size across all brushes.

* bug fix: was accidentally applying falloff curve to tiled mapping mode

== random rotation ==
*enabling random rotation gives each dab a random amount of rotation
* known problem: the overlay texture doesn't randomly reorient as well

* enabled jitter for position in sculpt mode

* changed brush_jitter_pos to find random positions within a circle instead of a square.

* moved icon and color options to their own 'Appearance' panel

* The new rake angle is now gotten by averaging the previous and current angles. This filters out some jitter.
