Message:

Correctly position windows in fullscreen mode (only works with CSR)

This involves translating the rendering operations as well as
hardware cursor operations and position events. This currently
only works with client-side rendering (using memory GC for translation),
but not with server-side rendering (need a new special GC to translate
the operations).
