[SDL] transparent blitting

[Phoenix Kokido]

I personally blit the individual characters of the font to a seperate
surface uncolorkeyed, then I color key that surface and blit it to the
display.  I have'nt actually done any testing to see if that's faster,
but I don't want to do a bunch of transparent blits.  The actual color
key is usually something easy to remember, like 0xFF, 0xFF, 0xFF, or
0,0,0, or just one channel set to 0xFF.  And I usually load it in the
gimp to make eliminate any stray pixels that antialiasing screwed up.
