Julian Smart 2a2a71e326 Applied patch [ 642172 ] Fix menu accelerators in ownerdrw
Fixed bug when updating menu text to inform the
ownerdrw code of the new menu accelerator attached to
the menu item.
Improved the layout of the owenerdrw menu ownerdrw to
correctly account for menu accelerators, submenu
arrows etc.

Scott Pleiter

(Note from JACS: I've also changed the sample to show the Quit item
correctly aligned; it needs to have the font set before wxWin knows
it's an ownerdrawn item.)
