Fixed several aspects of the GEOS CONIO implementation:

- cputc was drawing at the wrong position, therefore one line had to be removed as a workaround.
- chline, cvline were drawing one pixel to large lines.
- cclear was drawing an in both directions one pixel to big rect.
- the cursor was drawn at wrong times at wrong places in a wrong size.
