2004-12-27 Karl Runge <runge@karlrunge.com>
* allow -DLIBVNCSERVER_HAVE_FOO=0 override everything
* get_xfixes_cursor() try to more carefully convert alpha channel
to opaque pixel. Options -alphacut, -alphafrac, -alpharemove
* more commands under remote control: rfbwait, rfbport, http,
httpport, httpdir, enablehttpproxy, desktop, alwaysshared,
dontdisconnect. Add to tkx11vnc.
2004-12-22 Karl Runge <runge@karlrunge.com>
* final polishing for 0.7 release, tkx11vnc tweaks
* more careful rfbPE in pick_window, start check_user_input4()

Misc:
Since x11vnc has so many settings and to avoid further confusion,
the libvncserver options:
-alwaysshared
-nevershared
-dontdisconnect
are not available for changing in a running x11vnc (even though it
is feasible). These options overlap with the x11vnc options -shared
and -forever which are hopefully enough for most usage. They may be
specified for x11vnc startup if desired.

.PP
\fB-alphacut\fR \fIn\fR
.IP
When using the XFIXES extension for the cursor shape,
cursors with transparency will not be displayed exactly
(but opaque ones will). This option sets n as a cutoff
for cursors that have transparency ("alpha channel"
with values ranging from 0 to 255) Any cursor pixel with
alpha value less than n becomes completely transparent.
Otherwise the pixel is completely opaque. Default 255
.IP
Note: the options \fB-alphacut,\fR \fB-alphafrac,\fR and \fB-alphafrac\fR
may be removed if a more accurate internal method for
handling cursor transparency is implemented.
.PP
\fB-alphafrac\fR \fIfraction\fR
.IP
With the threshold in \fB-alphacut\fR some cursors will become
almost completely transparent because their alpha values
are not high enough. For those cursors adjust the
alpha threshold until fraction of the non-zero alpha
channel pixels become opaque. Default 0.33
.PP
\fB-alpharemove\fR
.IP
By default, XFIXES cursors pixels with transparency have
the alpha factor multiplied into the RGB color values
(i.e. that corresponding to blending the cursor with a
black background). Specify this option to remove the
alpha factor. (useful for light colored semi-transparent
cursors).
