OSX backend for SDL has had lots of problems that haven't been
Hatari related, SDL OSX support is just buggy.


There are very little things that can go wrong with Hatari SDL GUI
text drawing, as it's just about blitting pieces of 8-bit font surface.

To test whether 8-bit surfaces work otherwise, you can test whether
Hatari monochrome and VDI modes work, and whether forcing Hatari
to 8-bit with "--bpp 8" breaks something else[1].  If not, my guess
is it is something related to color key as that is used only with fonts.

The related code is in src/gui-sdl/sdlgui.c.

[1] in 8-bit mode colors used by emulated Atari can affect also
    statusbar, that is to be expected.
