Solve pie menu selection not refreshing properly sometimes.

Reason here is that double press events could get chewed on handler
level. The issue Added an extra flag to hanldlers so that we can choose
to handle if we want.

Also cleanup debug messages

Some cleanup, refresh pie direction and drawing on the same events that
fired the pie menu, also some debug prints. Note, this is not ideal,
normally we want to just ignore those events, will look into that later.

minor refactoring and all pie operators return finished.

Set the area rectangle to the whole screen area that spawned the pie
menu.

This means menus are now clipped correctly and their events are handled
in the whole area too, not only inside the bounding box of the buttons.

Cancel the pie menu when releasing without a valid item selected.

For ease of testing, move object mode switch pie to be active across all
modes. Also modify custom python example pie and put it to Q key, sculpt mode.

* Slight change on widget_box
* Pie menu operators return 'finished' to avoid evoking other operators
(maybe should be added to regular popup menus too?)

UI changes:

* Central widget does not depend on width of menu text.
* Menu name hovers above the central widget.

Add generic python operator that spawns a pie menu for a specific
operator enum.

Slightly offset the angles of diagonal pie menu items. Gives a more even
result. There may be a more accurate formula here but that works well
enough for now.

Press and release style interaction for pie menus

works by sending enter press and enter release events. May be somewhat
hacky but it should work.

+ minor cleanup.

Merge branch 'master' into pie-menus

fix blenderplayer compilation

Nice little widget indicator influenced from pie menu add-on

Pies:

* More display code
* Add collision detection in one more place, now object mode pie
collision works correctly.
* Changed object mode pie shortcut to TAB

Refresh the pie area always on mousemove

Angle range based collision detection on pie menu radial items. Also
some code to draw a central widget as well.

Detect intersection of buttons with big segment from center of pie menu.

This already starts feeling like a pie menu. A better model for
intersection might be to store a direction for the pie menu widgets and
check if cursor is within the designated angle.

Also python menus don't work too well yet.

Do not align pie menu item text on the left. Also some minor cleanup
