Hi,
Gnome-mag has a "cross-hair" feature for helping users find the mouse
cursor. An example graphic can be viewed here:
http://clown.atrc.utoronto.ca/aegis/GS-Mag/CrossHairs.png
The issue is that the cross hairs cannot obscure what lies beneath
them. As you can see in the png, the colours of the cross hair are
blended with the background.
Is colour blending possible within GnomeShell? My approach would be to
use clutter texture objects to form the cross hairs -- are there colour
blending functions for texture objects? I've looked at the online
documentation (http://www.clutter-project.org/docs/clutter/stable/), and
found transparency manipulations, but that's probably not enough.
Should I be diving into COGL? Looking somewhere else?
Any advice would be appreciated.
