- It might, actually. But you may not want to use that resolution...:-)
- For X (and for most other window systems) you may want to reserve some
- off-screen storage to cache fonts and small pixmaps. If you go to
- 1152x900x64k on a 2MB frame buffer, you have nothing left over, which
- means blitting characters over the ISA bus. The best theoretical
- performance would then be that of a passive monochrome frame buffer on
- the ISA bus. With font caching you transfer META information, which is
- independent for example of the font size (unless you run out of
- off-screen area).
