[wx-dev] wxGraphicsContext roadmap

[Stefan Csomor]

Hi Bill

yes, that's the idea, why cairo is in generic, so it should not be too much work to use it on any other platform that has cairo installed.

We have first to verify the proper solution on the pixel-center issue. So that the three existing backends behave accordingly. There are many plans, the different backends you describe, an extension of the object model along the lines of svg, native representations for bitmaps and linelayouts (like there are now for brushes et al) for best performance, svg reading, interactivity support etc.

But alas, free time is not abundant, and unfortunately there are other very important things to solve in the future for wxMac as well, so things arrive in small pieces only ...

Thanks,

Stefan
