Marc,
thank you for your message.
Cairo-SDL can be realized in two ways:
// Integrate SDL into cairo
http://www.cairographics.org/SDL/
// Use the integration (even if this is not up to date - this may help
me to understand)
http://cgit.freedesktop.org/~joonas/cairosdl/tree/README
Regarding the canvas I did not find any up-to-date implementation of
Quarz in C. We will need to use some wrappers in Obj-C exporting the
relevant funtions. I would try to make such an implementation, once I
understood how this works. But I did not understand why there are so
many more funtions implemented in sw_canvas.c compared to gdi_canvas.c.
Is there not the need to implement them all at present? If I want to
start with a kind of "quarz_canvas.c" - what would be the minumum set of
functions?
Kind reagards,
Mario

Hi,
I just compiled the spice-gtk client (spicy) on OSX
(http://www.spice-space.org/page/OSX_Client/Build).
I am able to connect to the spice server using this client but it is
more slow than any VNC client I know.
I looked into the code and found two different places where this
client
seems to be different than the x11 or GDI versions:
1.) It uses sw_canvas.c
2.) It uses spice-widget-cairo.c
Is it possible that the slow rendering results in the execution time
one
of those two files? Which investigation would make more sense: Would
it
be better to provide a SDL cairo version or should it accelerate the
What is "a SDL cairo version"?
client when there is a canvas option optimized for OSX (quarz I
guess)?
Gtk+ uses Cairo for drawing. If it's slow on OSX, it can probably be
optimized by using the right drawing API.
Is it possible to test the gl canvas on OSX? I didn´t found anything
about the gl implementation in the configure script.
Spice-gtk doesn't support GL canvas yet. The GL canvas is more limited
that the SW canvas, and it is generally much slower for today
computers.
