[AD] I've made a modification to the set_gfx_mode function

[Evert Glebbeek <eglebbk@xxxxxxxxxx>]

Hi people,

following the addition of GFX_AUTODETECT_FULLSCREEN and
GFX_AUTODETECT_WINDOWED in Allegro 3.9.37, I've modified the set_gfx_mode
routine so that if GFX_AUTODETECT_WINDOWED is passed, it will look for a
`gfx_cardw=' config string before `gfx_card=' and if it finds `gfx_cardw',
it ignores `gfx_card'. In this way, it is possible to specify a default
driver for windowed mode as well as an overall default driver.

I think this would be something that is generally useful, so I'd like to
request that it be integrated in Allegro, if no one else has come up with
something similar.
I understand that if I want my modification to be included, I should submit
a patch. How could I create a patch file and where should I submit it?

Please not that I have not (yet) subscribed to the mailing list, so please
CC any messages to my private email adress.

Best regards,

Evert Glebbeek
