On cursor theme and size

[Emilio Pozuelo Monfort]

Hi,

I was looking at why gtk+ clients use a different cursor theme and
size than other (toytoolkit) clients. gtk+ hardcodes the cursor size
to 32 as it has no way to get the preferred (default) size from the
compositor.

I guess one solution would be to have get_default_cursor_theme and
get_default_cursor_size requests in the desktop-shell interface
that desktop compositors implement. Then clients can get those
values and respect them if they so desire (and they probably do).

Or we could make this more general as in bug 49021[0] and have a
"settings" interface.

Thoughts?

BTW while at this I've made weston respect a new cursor-size
config key (similar to the current undocumented cursor-theme).

See also this analysis by MoD[1] and his two patches[2][3] (that
apparently went unnoticed) that also try to put some order to
cursor configuration.

Regards,
Emilio
