Fix various problems with constrained windows and/or custom frame windows:...

Fix various problems with constrained windows and/or custom frame windows:
* Wrong titlebar height
* Titlebars not handling custom font size properly
* Drawing errors in maximized mode
* One-pixel overlap glitch on bottom corners of client edges
* Borders not handling custom border sizes correctly
* Unnecessarily small top resize area (unlike in the main window, there's no competition here between resizing and window dragging in the same small strip)
* Wrong icon sizing (only a problem in theory, no one uses this code ATM)

These files are now very much like simplified versions of the opaque_non_client_view.cc code (which was the goal); eventually all these should be refactorable.
