[Qemu-devel] [PATCH] ui/vnc: Only report/use TIGHT_PNG encoding if enabl


From: Joel Martin
Subject: [Qemu-devel] [PATCH] ui/vnc: Only report/use TIGHT_PNG encoding if enabled.
Date: Wed, 16 May 2012 17:54:25 -0500

If TIGHT_PNG is not enabled by the --enable-vnc-png configure flag
then do not report to the client that it is supported.

Also, since TIGHT_PNG is the same as the TIGHT encoding but with the
filter/copy replaced with PNG data, adding it to the supported
encodings list when it is disabled will cause the TIGHT encoding to be
used even though the client requested TIGHT_PNG.
