Failure to find FLTK dependencies is only fatal for our version of FLTK.
When using the system version we have to assume it's built the way the
user wants.

Our FLTK patches modified FLTK's autotools-based build system so that HAVE_XFIXES and HAVE_XCURSOR were defined in FLTK's config.h, but those changes never made it into the CMake-based build system used by the in-tree version of FLTK. Further, our build system was allowing silent failures whenever Xft, Xinerama, Xcursor, or Xfixes were not present on the build system. Now, the lack of these libraries is treated as a fatal error, since these libraries are critical for TigerVNC functionality.

Changing the deferred update timer to 10 ms caused a large performance regression on video/3D apps, and until we can quantify the benefits of a larger DUT value, it was decided that it should be changed back to 1 ms for the 1.2 release.

We need to explicitly trigger a framebuffer update for server side rendered
cursors. Previously this happened to work anyway because we had a lot of
triggers for updates. After the cleanup, we need to be more explicit.

Grabbing the RGB components from the BufferedImage one at a time and converting the to a 24bpp RGB color manually is about 25% faster than using BufferedImage.getRGB().

Sync up java Tight decoder with recent changes to C client as much as possible. These changes should also fix the 16bpp issue reported in bug #3429667. I think there are probably errors in the FilterGradient* code but I can't get any servers to actually send this type of data to test it.

Increase the default compression level to cater to a broader range of users
(bandwidth is often the limiting factor, rather than CPU). Further increases
give little returns, so 2 is currently deemed the best tradeoff.

The block size for the comparing update tracker was inefficently low. Raising
it from 16 to 64 pixels significantly reduces the CPU overhead in many cases,
without sacrificing much in what it detects.

Make the comparing update tracker a bit more flexible. It can now be in an
"auto" state where it will be enabled until we deem that the client is better
of without it (currently triggered by explicitly stating a low compression

Also grab the mouse pointer in full screen as some window managers like to
do special things with buttons combined with modifiers. The user probably
wants to propagate these to the server though.

Send a move event when the pointer leaves the viewport as it makes it much

The CopyRect encoding is very efficient so it is wasteful to check those
areas here. It also makes the CUT counter-productive in some cases as it
tends to expand small changes to BLOCK_SIZE (16 pixels) because of the copy
regions.

Cork the outgoing TCP stream while we still have messages to process. This

Some platforms (I'm looking at you, MinGW64) have gettext but not iconv, so the build fails because iconv.h is missing. Thus, disable NLS if either gettext or iconv is not found.

Fix legacy-friendly build (I hope). r4745 (enabling DPMS) removed -DNO_HW_ONLY_EXTS from Xvnc_CPPFLAGS in unix/xserver/hw/vnc/Makefile.am, which caused xorg-xserver 1.6.5 to attempt to build the XFree86-DRI extension, but the stub for
XFree86DRIExtensionInit() was missing, so Xvnc failed to link. Adding --disable-dri (r4765) caused the GLX build to fail, because GLX needs either DRI or DRI2, and DRI2 was not being properly detected because the dri2proto module we were using was too old for our X server version.

If the client and server are using identical pixel formats, then perform Tight decoding directly into the viewer's back buffer, rather than going through the slow fillRect/imageRect routines.

Improved TightJPEG decoder by using a BufferedImage. It simplifies the code, and even though it's just used for grabbing the pixels, it should be faster since it can be HW accelerated. Also added a super.finalize() to the finalizer method in the ZlibInStream class for good measure.

This is subtle, but add_definitions() also adds definitions to the windres command line when building with MinGW, and this causes subsequent barfage because windres doesn't grok the -static-libgcc flag.
