Hi dotgnu-hackers,

using cairo is prettty much the why the mono project would like to
implement SWF now after they droped the wine approach.

Why should dotgnu/mono invent the wheel new?
Do you think that it would make sense to work together at this issue?

Regards,
 Thomas

That will cause race conditions and screen artifacts due to the round-tri=
p=20
time to the server: if another window moves over the drawn area while you=
 are=20
manipulating the fetched image, then you will get invalid pixels in the a=
rea=20
that is uncovered.  It is also hideously inefficient.

The Xrender extension and/or Cairo is the correct way to do this, which w=
e=20
will tackle only after everything else works correctly.  The work needed =
is=20
mostly in System.Drawing.Xsharp and Xsharp, so it should not affect anyon=
e=20
working in System.Windows.Forms or System.Drawing.

Cheers,

Rhys.
