since its a variant of UI_fontstyle_draw that skips shadow, align... etc.
Currently this is mainly useful for picking camera DOF depth.
- EKey over a distance field prompts you to pick a depth from the camera.
- WKey (Specials menu) to pick from the 3D view (when the active camera's selected).

- API function calls
- enum values
some internal static functions have been left for now
Either was some residue from the past or somebody didn't implement this in
the right way.
Also fixed memory leak in ED_space_clip_color_sample() caused by missing
image buffer release.
