that's not what i had in mind. it's not much of a change from the current
system and IMHO not worth the work to implement it.

that's more like it. some elaboration explaining my current proposal
follows:

- to have a second std_gfx_mode_list list pointer which points to a list of
the typical 'standard' modes which you can already select from the
gfx_mode_select* function and use this when get_gfx_mode_list is not
supported for the given driver. a clean solution which relies only upon mode
lists.

- remove the current system where you select a driver, resolution and
eventually color-depth. this should be replace with a driver selection
dialog and a combined resolution/color-depth dialog made from the mode
lists. i suppose i could provide a flag to switch between the old and the
new methods if that would be preferred among some users.

- mode lists could be pre-fetched and stored in memory (and later freed upon
exit from gfx_mode_select*)... that depends on how fast a get_gfx_mode_list
can be done. i doubt it will be neccessary though.

- the possibility to input custom resolution for windowed drivers, perhaps?

we still need them as not all drivers support gfx_get_mode_list(). a way to
select resolution and color-depth but leaving the job of choosing a capable
gfx driver to allegro.

anyway, this is a rewrite which will (!) be done. therefore i need some
feedback. aside from the general redesign, what options will be worth
having/keeping and are there some things i didn't think of?
