if you switch from a Drawable to a cairo_t* engines will have to be
rewritten - but they will also still have the issues they have right
now. the real plan is to actually address the issues, not paper over
them by having gtk+ call gdk_cairo_create() for the theme engines.

that it's pointless? a useless papering over real issues?

you seem to be under the impression that changing the API of the theme
engines is not going to require an ABI bump - which is still problematic
to handle from a loadable module perspective, and the gtk+ maintainers
are not really looking forward to the mess it causes (especially with
poorly maintained third party themes).

gtk+ 3.x is the occasion to bump API *and* ABI, so time and effort
should be spent into looking at ways to solve issues of the 2.x API.
