* Changes in interface/ module This commit brings back the way how buttons/menus work under control of WM event system. The previous implementation extended usage of handlers and operators in an interesting but confusing way. Better to try it first according the design specs. :) Most obviously: - modal-handler operators are not stored anymore in regions/areas/windows. such modal handlers own their operator, and should remove it themselves. - removed code to move handlers from one queue to another. (needs review with brecht!) - WM fix: the API call to remove a modal handler got removed. This was a dangerous thing anyway, and you should leave that to the event system. Now, if a handler modal() call gets a cancel/finish return, it frees itself in event system. WM_event_remove_modal_handler was a confusing call anyway! Todo: - allow button-activate to refresh after using button - re-enable arrow keys for menus (do both after commit) - review return values of operator callbacks in interface_ops.c * Fixes in WM system - Freeing areas/regions/windows, also on quit, now correctly closes running modal handlers - On starting a modal handler, the handler now stores previous area and region context, so they send proper notifiers etc. * Other fixes - Area-split operator had bug, wrong minimal size checking. This solves error when trying to split a very narrow area. - removed DNA_USHORT_FIX from screen_types.h, gave warning - operators didn't get ID name copied when activated, needed for later re-use or saving.
