Hello,
this is a program you will find very useful, if you have an AMIGA equipped
with ECS or AGA.
Have you ever changed your monitor driver with MonEd or the like ?
Perhaps you have noticed that if you increased vertical/horizontal resolution
about the overscan limit you can have a larger view as your max overscan.
But if you move the mouse beyond these overscan, the screen scrolls (if you have
autoscroll on). If you haven't autoscroll on, the mouse stops at max overscan !
Silly, eh ?
So, increase the max/video overscan with this program and your screen scrolls
no longer.

It can change the overscan settings for video, max, and nominal overscan.
So you can, e.g. change the vertical overscan on the EURO36 monitor.

Template:
PatchOverscan ID=MODEID/K/A O=OVERSCAN/K/A MINX/N/A MAXX/N/A MINY/N/A MAXY/N/A

ID:   a monitor id, like in include:graphics/modeid.h
			(find it out with ModeIDList (also included in this package))
O:    overscan type, one of N (Nominal)
														M (Maximal)
														V (Video)
MINX: lower horizontal bound for overscan rectangle (can be < 0)
MINY: lower vertical bound for overscan rectangle (can be < 0)
MAXX: upper horizontal bound for overscan rectangle (must be > MINX)
MAXY: upper veertical bound for overscan rectangle (must be > MINY)

Example:
PatchOverscan ID=79000 O=M 0 0 719 299

This gives you a max overscan of 720 * 300 for the "EURO36: HighRes" screenmode.
Start "Prefs/Overscan", select "EURO36" and now you can edit between 640 * 200
and 720 * 300 pixels.

Best place to start this program is in your s:user-startup, but it must be placed
after IPrefs !!

NOTE: This is a HACK and will not work for standard PAL and NTSC monitor
drivers, because they don't seem to build a fully featured entry in the
display database.

NOTE2: This is a simple program.

Tech:
This program uses an undocumented function of the AmigaOS, so don't
expect it to work with future versions of the OS. (>3.1)
This was compiled with SAS/C 6.56 on an A4000/030 with 10 MB RAM, ARXON Scandoubler,
Cybervision64 (not yet functional...), Monitor miro D1786T (30 - 86 kHz).
