Win32 support > 8bpp ?

Running through the initial demos, and I can't get any GUIX Studio project to compile, if I use anything above 8BPP, I get linker errors when looking for a class of drivers called. " win32_dave2d_graphics_driver_setup_xxxx"

Googling for "Dave2D" graphics driver brings is literally nothing, and there is no mention of this on the GUIX site.

For now, sticking to 8BPP fixes the issue, however confused, what have I missed?

    Issue:  

    Running through the initial demos, and I can't get any GUIX Studio project to compile, if I use anything above 8BPP, I get linker errors when looking for a class of drivers called. " win32_dave2d_graphics_driver_setup_xxxx"

    Solution:

     The "fix" is to not use Dave's drivers, but use one of the others defined in gx_win32_driver.h , selecting the correct one based on your GUIX Studio display depth setting.
