Well, I'm still trying to get a program that will write a BMP file under
Linux, so I can test my code so-far.  Currently, it draws a playing field,
loads up a couple of buttons (eg. Quit and New Game), the quit button was
working, but that was before it was actually something apart from a blank
screen. (Yes, I know SDL can write a BMP, but I'm not going to write a paint
program...)

Also, I didn't see any sample code for moving objects...  I want to move a
block (eg. not animate, as that would kill the tetris semantics) down, but does
that mean that I have to blank out where it used to be, draw where it will be
and then do a SDL_UpdateRects(), or am I missing something?

<Constructive Criticism>
I'm still trying to get the hang of how graphics APIs work in general, and the
SDL docs are great, if you want to draw an individual pixel or a BMP at the
place where the mouse clicks or something silly like that, but it doesn't
explain things well enough that you can actually understand what each function
is doing. (or explain what a "blit" is, for that matter)
</Constructive> (I've gotta go to work soon, so no more constructiveness today)

BTW, in the design, my program will be the first Tetris clone (that I've heard
of) with themes support...
