Some problems during/after 1st wayland build

[Knut Petersen]

Hi everybody!

Some comments / suggestions / bug reports:

1: http://wayland.freedesktop.org/building.html misses that building weston
will fail without a recent libwebp from http://git.chromium.org/webm/libwebp.git.

2. http://wayland.freedesktop.org/building.html misses that after building weston
"make install" needs to be run as root.

3. Weston needs an xcursor theme to be installed and accessible via
~/.icons/default/index.theme, otherwise no cursor will be visible. That
probably also should be mentioned in http://wayland.freedesktop.org/building.html
as a lot of people don´t have it on their system.

4. After solving problems 1-3, weston and the weston demo clients like gears
worked fine if weston was started as an X client. Without X weston started as
a normal user blocked keyboard and mouse, so a power button reboot or killing
weston via ssh was necessary. Weston without started as root worked fine.

5. I know, (glx)gears is not really a benchmark as fps is limited by vsync. But here on
an idle system fps(~45) stayed 25% below vsync (60).

6. Occasionally short bursts of screen distortions are visible if weston is started
without X.

7. http://wayland.freedesktop.org/xserver.html worked fine as a guide to build x client
support, but every X client I tried killed weston:
