-
- While both X and Windows support drawing lines and arcs, Microsoft would be
- foolish to pick the X rules for arcs (*very* hard to do both right and fast),
- and I doubt they share the same rules for wide lines (I think X's wide line
- rules are Ok).
-
- A graphics engine tuned to X would most likely omit the many Windows drawing
- modes that X doesn't support (say, GXadd [I don't know what Windows calls it,
- I'm an X guy]).
-
- However I can't think of any way in which the 4000/W32 could be bad for X
- that the S3 wasn't. (it could include more windows stuff 'tho) Except for
- devoting a larger part of the chip for stuff useless to X...
-
- Of corse alot of what speed up Windows speeds up X. Copy bitmap across the
- planes is just X's CopyPlane. Accel'ed lines can be used for X's 0-width
- lines. Stuff to speed up Windows text should speed up text for any 8-bit
- X fonts (and there are few 16-bit X fonts). And of corse you could make an
- X extention to use the Windows style raster rules...
