DynaMate 0.5
                             by Ville Rannikko

DynaMate is a simple Dynamic-Hires picture display program. DynaMate
will show any size of Dynamic-Hires pictures and will enable you to
scroll pictures that are bigger than screen. Scrolling is done by 
moving your mouse and the program exits when you press left mouse button.
DynaMate won't show Dynamic-HAM pictures. I don't think that is needed
because you can use use SHAM mode to get almost the same results and 
Mostra can show SHAM pictures. When converting pictures with Wasp remember
to use '-hires' option to make the pictures use 4 planes.

DynaMate shows only 608 pixels, because otherwise copper cannot change
all 16 colors during the horizontal blanking. Dyna-Show changes only 8
colors with copper. The 8 other colors are changed with processor, to
make that kind of thing work on all Amigas requires a lot of hacking.
So I used a narrower screen to make my coding task much easier.

I have only tested this program on an Amiga 500 with kickstart 1.3, so I
don't know if this will work on any other Amigas. Bug reports and

History:
0.1 Initial public test release. Not a very wise move.
0.2 Rewrote almost everything to use only system function. This one was
    really slow and I found no cool way to make the scrolling work.
0.3 Back to direct hardware access. 
    New:
    -image is centered
    -flicker free scrolling (I hope)
0.4 There was a bug that caused a possible call to dos.library
    before it was even opened. That is now fixed.
    Also fixed a stack problem.
0.5 Seek() errors were not correctly handled, fixed

    Bugs/Features:
    -screen position should be read from preferences, but I use always
     ($81,$2c)
    -moving mouse rapidly around will cause funky scrolling effects
