TODO

8.8.04:
+ ANIM_ENGINE: ball should get squashed at bounce.
+ options menu // gernericize menu code
+ "Labels" in "Original" game background

16.6.04:
. higscores: empty name creates broken file
. every score gets at least last place
+ corrupt file breaks HS alltogether

24.2.04:
. Highscores are buggy.

7.12.:
. cheat -> no highscore
+ scores: flags (cheat, startinglvl?), howlong. sane printing of times.
+ font: right-justfied printing for numbers. perhaps fixed.witdhprinting?
+ end of levels -> random levels
+ saner handling of Scorefile brokenness/nonexistence.

+ Add better(complete) sound FX
  -> SFX added. Could still be improved.
. Add mini-animation engine
  (moving: ball, disk; stationary: stone_explosion, ball_explosion, "twinkle")
  [all done. "twinkle" is too expensive for now]
+ Add music (ingame, title, credits) (cecile?)
+ Add better stone models (rotfl?)
  . Round ball: use either png:transparent or
    color keying instead of current method.
    -> works fine with color keying.
+ Add better bg graphic
. Add layout description file & parser.
  (should now be in 'Settings' file)
. Add title screen,
+ Add credits
+ Add game rules description (perhaps in-game?)

? How to print level names? Use BFont? Use monospaced? Use COLOR_KEYING?
  . Wrote own font routine, uses proportional font. Transparency still missing
? color stones in-program or externally?
  (currently in-program, but may get complicated with shaded stones)
  shading works fine, but maybe make colors "Theme"-configurable?
? In printing routine, maybe add caching?
  How to decide when to use alpha? it is probably to slow to do that everywhere.
. Is it actually okay to use DBLBUF? or better single, and update_Rect?
  if really necessary, updated could be combined off-screen and copied.
  (heroes uses DBLBUF and is amazingly fast. So this seems OK)
. Should all graphic/sound things be changeable by level, or by 'Collection'?
  (by Collection, for now)
. Should the gamefield be completely static? Or e.g. the borders be
  pieces itself?
  (completely static, for now)
. should sound effects be all played, or cut themselfs off like in the
  original
  -> We only cut off effects of the same type.

. heroes is quite fast but yet doesn't use ANYFORMAT, but palette instead.
  perhaps their way of managing the screen themselves and just telling SDL 
  to update the entire screen at once is a performance gain?
. We use UpdateRect now, and it seems this is fast enough...

bug: If you keep an arrow key pressed during a level change/restart that
     direction gets cleared.
bug: hit two "stars" or "disks" at the same time (in a corner). In the original
     only one disk moves. (not 100% sure about stars)
diff: original game contains different 'Wall' blocks. No difference in
      gameplay, just for visual effect.

. timing on linux seems off. The game feels too fast.
  [have improved Delay handling with busy waiting]

? steal some graphic effects from heroes?
? should the ball deform itself on impact?
  (original does that on top and bottom)

? find out when extra lives are granted
