Thanks for the explanation :-)

So it seems there is in fact demand for a new tool - even for the C64:

- Running on the cc65 host (not target) platforms
- Reading a BMP/PNG/...
- Writing a device dependend bitmap (hopefully supporting many TGI drivers)
- The bitmap contains some minimal header with height and width and ...
- Hopefully many TGI drivers support copying "their" bitmap to a drawpage

So it's basically a 1on1 between the driver-specific tool-backend and
the driver "copy" code.

Something like this seems useful to me...

Best, Oliver
