[mythtv] [PATCH] Overscan for GUI

[David =?unknown-8bit?Q?H=E4rdeman?=]

Hi all,

to get some variation from writing SQL patches, I looked into another of 
my pet peeves this evening, GUI overscan.

Currently, the menus (especially in configuration) likes to extend to 
the edges of the screen which is fine for a computer monitor but gives 
problems on my TV (which is not completely square).

The result is this patch:
http://www.hardeman.nu/~david/mythpatch/gui-overscan.patch

which is not in a commitable state yet, but it should work 
good enough for people to test it. The overscan setting is in the 
appearance menu together with the display size settings.

What is left todo is to make the overscanned menus draw a background 
which blends nicely with that of the main window (hard to explain but 
you'll see the problem if you try the patch), and to make sure that it 
doesn't break any random screens (only tested it lightly so far).

Feedback, testing and suggestions of how to fix the background problem 
are all equally welcome.
