[Bf-blender-cvs] SVN commit: /data/svn/bf-blender [30626] trunk/blender/source/blender/ editors/sculpt_paint/paint_image.c: this fixes the bug that occurs when using pen tablet controlled pressure and the first daub is at maximum pressure - the bug is actually in brush_painter_paint (BrushPainter *painter, BrushFunc func, float *pos, double time, float pressure, void *user) according to brecht, but ' seems more complicated than expected to properly fix this' so this work around has been approved
