Greetings...

I've more or less just now brought down the GRXlib, got the examples
running and started to do some coding with it. This has lead to some
questions (some of them I'll probably figure out myself sooner or later,
but if there's some wise and friendly soul around that could enlighten
me in these issues, it'd save me some time and thinking, something I'd
really appreciate).

First of all, I'd like to, in the fastest and easiest way, just flush an
unsigned char buffer with pixel data (in other words, a large bitmap)
onto the screen. (1)

I haven't yet found a really easy way to do it, but I suspect it could
be fairly easily done using contexts. If so, new questions arise. Can a
context be convinced to use my pixdata when being blitted? (2) And if
so, how do I convince it of that? (3)

Furthermore, I've seen some indications that GRXlib supports the famous
ModeX format 320 x 240 x 256 (pixels SHOULD be squared) and some
indications that it's not yet completed. If anyone could give me some
information about the situation and how to get ModeX I'd really
appreciate it? (4)


Again, I'd really appreciate any help and enlightment on the four issues
above.

Thank you in advance,

J Wenzel
