This is needed for popups to chance state once activated,
currently it makes use of operators `check` callback, after values are modified,
as the file selector does already.
View2D had some inconsistencies making it error prone in some cases.
- Inconstant checking for NULL x/y args.
Disallow NULL args for x/y destination pointers, instead add:
- UI_view2d_region_to_view_x/y
- UI_view2d_view_to_region_x/y
- '_no_clip' suffix wasn't always used for non-clipping conversion,
switch it around and use a '_clip' suffix for all funcs that clip.
- UI_view2d_text_cache_add now clips before adding cache.
- '_clip' funcs return a bool to quickly check if its in the view.
- add conversion for rectangles, since this is a common task:
- UI_view2d_view_to_region_rcti
- UI_view2d_region_to_view_rctf
Enum icon-only buttons were getting their strings set,
then truncated with blenders string shortening methods, then not drawn
because there was no room (since buttons are icon width).
Modify UI code so icon-only buttons don't get names and passing "" to a
button won't have its text set later on.
Adds some padding to the left of the icon, adds more space around the separator
line and make it more visible, and add some spacing at the top and bottom of
the menu. Ref T37794

- works by defining panel categories, currently restricted to the toolbar.
- no panels define bl_categories yet, so no user visible changes since tabs only show when there are multiple.
- panel pinning is available in rmb menu or alt+lmb.
Before it was giving weird behavior with timeline in MCE
and track preview widgets. But there's also no much benefit
of having transparent toolbox there.
Requested by our motrack guru Sebastian ages ago.
Summary:
- Fixes an off-by-one error in screen_test_scale() which causes the areas and
regions to draw one pixel bigger on the right and top side of the window,
therefor hiding one line of pixels.
- Fixes an off-by-one error in rct_fits() which causes regions to incorrectly
hide even though it would fit inside the area.
- Correctly set the limits for the screen edge move operator so it will always
go up to AREAMINX and headery.
- Change screen_find_active_scredge() so it doesn't show the arrows cursor on
the screen edges along the window border.
The import thing to understand is how integer rects are used in this part of the
code. They are constructed as a lower left and top right point and are INCLUSIVE.
Meaning that if you have a rect's xmin = 10 and xmax = 30 then the total number
of pixels is 21. So to get the size of a rect you have to do xmax - xmin + 1,
which is easy to forget and result in off-by-one errors.

node materials.
Area and region listener callbacks now get the screen and area pointers passed, so
they can do more fine grained checks to see if redraw is really needed, for example
depending on the 3D view drawtype.
* RNA's editor types enum (space_type_items) has been re-ordered, added icons, and removed internal-only SPACE_EMPTY value, so that it matches the menu.
* Two fixes in code drawing enums as dropdown menu:
** All items were taken into account when computing the number of needed columns, now simple separators (void string items) are ignored.
** Simple separators items were drawn as labels, taking far too much space!
And now translators will be free from that ugly, insane menu-string! :P
Thanks to Brecht for the review.
Partial redraw doesn't work so well with these, now I've changed the action
zones to just draw as part of regions instead of as a special overdraw done
at the end, which fits better with partial redraw by avoiding any special
exceptions.
