wxGraphicsContext roadmap

[Bill Baxter]

What's going on with wxGraphicsContext these days?  Is there any
roadmap?  Any new features planned for the next release?

I've been using it myself, and I'm starting to think it might be a
good idea (as has been suggested by others) to have a cross-platform
back end based on say Cairo or Agg 2.4.  I'm not saying to get rid of
the other back ends, but just to make it an option for anyone wanting
to have truly pixel-for-pixel identical results cross-platform.  Same
idiosyncrasies everywhere is better than different idiosyncrasies
everywhere. Maybe something like this is already in the works?  (I saw
something like a wxCairoContext in the generic directory...)  I guess
eventually there are also plans for wx{PDF,SVG,PS}Contexts as well?

Has there been any discussion about making a wxColourDialogWithAlpha?

I think wxGraphicsContext could also really use a topic overview that
explains the basics clearly, like what it means to
DrawRectangle(0,0,1,1) -- where are the pixel centers and that sort of
thing.  Also how is stroking affected by transforms?  And just giving
the lo-down on path-based graphics vs the standard wxDC graphics.
