- implements YieldFor() with event filtering for wxMSW and wxGTK, adds TODO markers in other ports; - replaces wxYield() in GTK's clipboard code with a wxTheApp->YieldFor() call, thus fixing possible reentrancies (and modifies clipboard sample to test synchronous IsSupported calls) - replaces wxYieldIfNeeded() calls in wxProgressDialog with wxTheApp->YieldFor() calls, so that it processes only UI/user-input events, thus fixing the race condition visible in the "thread" sample - documents the new functions git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@58654 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
