Differentiate between the clipping of the video stream, and the region that currently displays fragments of the video stream (henceforth, vis_region). The latter equals or contains the former one. For example, let c1 be the clip area at time t1, and c2 be the clip area at time t2, where t1 < t2. If c1 contains c2, and at least part of c1/c2, hasn't been covered by a non-video images, vis_region will contain c2, and also the part of c1/c2 that still displays fragments of the video. When we consider if a stream should be "upgraded" (1), due to its area being used by a rendering operation, or due to stopping the video, we should take into account the vis_region, and not the clip region (next patch: not upgrade by the last frame, but rather by vis_region). This fix will be more necessary when sized frames are introduced (see the following patches). Then, the vis_region might be larger than the last frame, and contain it, more frequently than before. (1) "upgrading a stream" stands for sending its last frame losslessly. Or more precisely, lossless resending of all the currently displayed lossy areas, that were sent as part of the stream. |

SPICE: Simple Protocol for Independent Computing Environments
=============================================================
SPICE is a remote display system built for virtual environments which
allows you to view a computing 'desktop' environment not only on the
machine where it is running, but from anywhere on the Internet and
from a wide variety of machine architectures.
Installation
------------
The SPICE package uses GNU autotools, so the build install process
follows the standard process documented in the INSTALL file. As a
quick start you can do
./configure --prefix=/usr --sysconfdir=/etc \
--localstatedir=/var --libdir=/usr/lib
make
sudo make install
Or to install into a private user specific location
./configure --prefix=$HOME/spice
make
make install
The following mandatory dependancies are required in order to
build SPICE
Spice protocol >= 0.9.0
Celt >= 0.5.1.1, < 0.6.0
Pixman >= 0.17.7
OpenSSL
libjpeg
zlib
Cyrus-SASL
The following optional dependancies increase the available
functionality
GE Gui >= 0.6.0, < 0.7.0 (GUI app support)
OpenGL (GUI app support)
Alsa (Linux support)
XRandR >= 1.2 (X11 support)
Xinerama >= 1.0 (X11 support)
libcacard >= 0.1.2 (Smartcard support)
Slirp (Tunnelling support)
Communication
-------------
To communicate with the development team, or to post patches
there is a technical mailing list:
http://lists.freedesktop.org/mailman/listinfo/spice-devel
There is also a mailing list for new release announcements:
http://lists.freedesktop.org/archives/spice-announce/
To view known bugs, or report new bugs, in SPICE visit
https://bugs.freedesktop.org/describecomponents.cgi?product=Spice
Bugs found when using an OS distribution's binary packages should
be reported to the OS vendors' own bug tracker first.
The latest SPICE code can be found in GIT at:
http://cgit.freedesktop.org/spice/
