Simple Sdl Test Touch Screen Program

[zx-81]

For those who wonder how to use the Wiz touch screen with SDL, here is a simple program i've developped before porting
"Wiz Write", in order to test the touch screen :

This simple test program use virtual keyboard images based on Danzeff keyboard i've used on PSP.
Using the touch screen you can click on the letter you want, and drawing a line vertically or horizontally
(on the virtual keyboard screen) you can navigate between the different keyboard panels.

Be careful not to modify default clock/CPU speed because it will modify the area of the touch screen
(i felt in this stupid issue at first and spent hours to understand why my touch screen didnt give me
the proper coordinates !)

That is cool. Hopefully some coders can make some good use of this. Thanks for the good utility
