Hello,
The attached patch is supposed to remove the bitmap scaler from
XFree86. It has only been tested with KDrive, not with the XFree86
server. I'm fairly confident it doesn't break XFree86, but I
wouldn't be surprised if it broke Xprt. (Not that anybody cares.)
I'll be glad to receive feedback before I submit it to David. If
there's any opposition, I can quite easily produce a much simpler
patch that simply disables the ability to scale bitmap fonts without
removing the code.
My suggestion for the release notes is as follows (edits welcome):
The support for scaling bitmap fonts is removed.
The server's ability to scale bitmap fonts confuses both users and
application developers. Many X installations are configured
incorrectly, leading to the familiar ``ugly fonts'' syndrome.
Recently, high-quality free scalable vector fonts have become widely
available; a number of such fonts are included with XFree86, others
can be found bundled with other software packages, notably Aladdin
Ghostscript version 6.0 and later. Because of that, the ability to
scale bitmap fonts is no longer needed, and has been removed from
XFree86, leading to much simpler server configuration.
Because of this change, you will need to remove any ``:unscaled''
attributes from your font path. Please check your XF86Config (or
XF86Config-4) file for any lines of the form
FontPath "/usr/lib/X11/fonts/misc/:unscaled"
and remove the ``:unscaled'' part, e.g.
FontPath "/usr/lib/X11/fonts/misc/"
