ee81da14d6 cx16: removed monochrome modes from gfx2 (use monogfx instead). New screen mode numbering!
programs will now be a lot smaller than before if they use gfx2 (or monogfx if they were only using monochrome drawing)
monogfx also fixes some drawing errors with small horizontal lines, and stippled vertical lines.

dd2463a440 proper fix for the previous commit. + fix for i/o channel reset in diskio.f_seek()
it wasn't the adressing mode, it was that it assumed the pointer variable was always in zeropage (which might not be)
