Bug#1010449: libvncserver1: Please support larger screens

[Reuben Thomas <rrt@sc3d.org>]

Package: libvncserver1
Version: 0.9.12+dfsg-9ubuntu0.3
Severity: normal

Libvncserver cannot cope with a single 8K screen or dual 4K screens etc.

The problem is that the value of UPDATE_BUF_SIZE defined in rfb.h is too
small.

See https://github.com/LibVNC/libvncserver/issues/521

It would be great if this could be fixed in Debian without waiting for a new
release. The fix is simple and doesn’t seem to cause problems: the amount of
memory required is modest and is a one-off cost per client connection.
