cairo_interaction::set_source_rgba() is not public about gdk HOT 5 CLOSED

@EPashkin I mentioned this in my PR for the RGBA stuff, but I figured I'd break it out as a separate issue. Any idea what's going on here?

Indeed, this looks to be a compiler bug. If I rename ContextExt::set_source_rgba to set_source_rgba2, then I can use that function in the connect_draw closure.

So here's the question, how do we want to resolve this? We have two functions, gdk_cairo_set_source_rgba and cairo_set_source_rgba. Is there a convention for how to handle duplicate function names within the gtk-rs namespace?

Pinging both @EPashkin and @GuillaumeGomez because I don't know how this should be resolved.

Looks like I was wrong, sorry about the noise! Just talked to some people on IRC and the proper way to use these functions is the do <Context as ContextExt>::set_source_rgba(&c, &foreground); where use cairo::Context; and use gdk::prelude::*; where used to bring both the struct and trait into scope.

So closing this.

IMHO ContextExt::set_source_rgba(&c, &foreground) will work too

The compiler complained about the types and using the explicit syntax fixed it.
