0.2
cursors are supported
source is now equivalent to TridiaVNC 1.2.1
pthreads now work (use the iterators!)
cursors are supported (rfbSetCursor automatically undraws cursor)
support for 3 bytes/pixel (slow!)
server side colourmap support
fixed rfbCloseClient not to close the connection (pthreads!)
pthreads now work
this is done lazily (and with proper signalling).
cleaned up mac.c (from original OSXvnc); now compiles (untested!)
compiles cleanly on Linux, IRIX, BSD, Apple
compiles cleanly on Linux, IRIX, BSD, Apple (Darwin)
fixed prototypes
0.1
rewrote API to use pseudo-methods instead of required functions.
