Just because it is a gerber it must be NOT antialiased

Actually yes... while photoplotters work at 8000dpi (typical), silk screening is A LOT less, maybe even around 200dpi. So hinting should be done... also a lower resolution means less vectors to output.

Reading http://docs.wxwidgets.org/stable/wx_wxfontoverview.html gives me the idea that there are still too much differences between platforms...

Also, under wxDC it says:

NB: under wxGTK the current logical function is used by this function but it is ignored by wxMSW. Thus, you should avoid using logical functions with this function in portable programs.

More and more platform incompabilities :((

If I get it correctly your opinion is to simply use OS support for the fonts... that could be OK for 'typical' applications but not for CAD (nor for typography :P:P)

Anyway, your plan should be something like:
- Get the font online (with wxFont)
- Render it on a backing store bitmap (using wxDC)
- On screen blit the bitmap, on plot rasterize it.

The intermediate bitmap is needed becausee Windows doesn't do XORed text (or so it says in the docs). If step 1) goes fine, all the rest should work...
