Comment 3 for bug 1182766

I'm not sure how to actually load those images if they are not read from the system location (i.e. if we ship them ourselves as part of the package), as Glade doesn't seem to load .svg files as images for buttons.

As a stop-gap measure for Ubuntu 12.04 users, we could use non-symbolic icons. They will not be consistent, but it will be better than having no icon. E.g.

- For the edit color button: applications-painting
- For the invert button: object-inverse

Or to make life easier, we could just go for these icons for all Qreator versions.
