Whoops, I forgot to make git track the GridMesh GLUT code. Here it is.

Proof of concept pie interaction:

Press for calling operator, hold to spawn pie menu.

Test on object mode operator, pressing TAB toggles to edit mode, keeping
TAB pressed more that the drag timeout spawns a pie menu.

Still needs a way to enforce the menu to not listen for further drag
timeouts but looks like the concept holds.

This is implemented using the previous operator,
WM_OT_call_pie_menu_timer, in a macro. When the calling button is
pressed too long, the operator is cancelled (thus cancelling the macro)
but spawning a pie menu before that. If the timeout is not reached and
a key release event is detected, the operator finishes and the macro
continues, calling the next operator instead (object mode set, in our
case).

Fix minor issue, pie menu is set as cancelled only for hold/release
style menus.

Experimental:

Add timer wm operator that spawns pie menus after a certain time.

For now this timeout is the same as the drag timeout, should probably be
a separate option

Tweaks to the central pie menu widget:

Adopt a disc based design, also serves to better identify the threshold
value for a valid selection and is now fully themeable.

Merge branch 'master' into pie-menus

Address review points:

* Deduplicate panel for texture paint brushes
* Use compare_len_v3v3_squared for color comparison in 2d fill tool
* NULL check when adding texture.

Correcting own mistake

Merging patch D610 - Fixes T30630

Refresh texture paint caches of materials on changing render engine.

This is not perfect yet - it would help a lot if we could restore the
node mode of a material when changing the render engine too, but this
is maybe for later.

Also did some naming cleanups - we have texture paint slots now for
materials, not images.

No changes, commiting because there was a problem with the way I uploaded the revision

Misc minor changes
- add WM_drag_free_list()
- use len_manhattan_v2v2 to compare point distance
- avoid calling BKE_scene_use_new_shading_nodes in a loop

Correct DM_DRAW_USE_ACTIVE_UV, was defined as (DM_DRAW_USE_COLORS | DM_DRAW_ALWAYS_SMOOTH)

also cleanup headers in paint_curve.c
