* Disable shaded mode for now, it cause too many crashes combined
with preview render, will be fixed properly later.
* Make 3d view toolbar region a bit wider. Ideally this would not
be needed, but the sculpt/paint buttons just don't fit otherwise.
* Revert change to icon/text spacing in buttons, it breaks text
editing and clipping. Will properly fix this later so changing
the spacing can be done centrally.
* Fix for grease pencil simplify stroke python error. Now button
is hidden (as in 2.4), but still available through outliner.
* Fix for memory leak in UI code, when using ctrl+Q menu.
* Fix submenu > icon being drawn on some buttons where it was not
needed.
