Help Needed


compound text encoding
keysym <-> keycode
test synchronization and multi-threading safety
color model

image loading


new x extension: server side image loading (given a filename/url
of gif/png/jpeg in a request, x server (instead of client library)
creates a pixmap and loads (and possibly decodes) data into it); no
need to transport large pixmap across network twice (netscape image
display)

use xie to decode jpeg? [keith said it's broken]

java native interface to MIT-SHM (check
/usr/include/X11/extensions/XShm.h) [undocumented; un-offical]





Credit

I came up with the idea of Java X11 library without knowing Boukanov's
or O'Neil's works. However, during the middle of development, I
discovered their presences and started using their codes as my
reference. Needless to say, I read between lines of all codes in C
xlib by X Consortium.
