Confidentially...  No, not really. ;^)  SDL handles double-buffering for you
in most environments.  Tux Paint's another story, but then again, most
of the things I draw onto the canvas (which is displayed within the window)
I NEVER draw _directly_ into the window, and vice-versa.)

I admit that I'm really not a very skillful software engineer.

My typical coding session begins with starting to code, rather
than thinking much about the design.


Of course, most of what I write are games, and are kind of 'disposable.'
Once I actually finish the project, it's finished, so I don't have to
deal with it much later - there's not much of a problem with scale.

(A few examples come up where scale was a big issue, and I've never finished
the game.  BoboBot and Super Tux come to mind.  But, I vow to one day
complete them!)

-bill!
