* Fix regression caused by r4841. That patch assumed that JPEG encoding ↵DRC2012-02-133-45/+47

Reorganise and clean up the code to handle this, and make the raw frame buffer pointer const so that we might avoid such bugs in the future. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4841 3789f03b-4d11-0410-bbf8-ca57d06f2519

| | | | | | 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. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4834 3789f03b-4d11-0410-bbf8-ca57d06f2519
