 +====== FLI Floffy ======
 +
 +{{flifloffy.png|}}
 +
 +
 +===== Concept =====
 +A FLI logo is sine-waved first on the Y axis (DYPP) and then on the X axis (tech-tech.)
 +The most tricky part of this is that in FLI, the colors and bitmap are interconnected in every 8x1 byte, as well as in every char.
 +So it's hard to shift single rows of pixels up'n'down independently, without getting color clashed.
 +And even if the graphics was designed to avoid this, the process would be rather cumbersome rastertime exhaustive.
 +
 +To get around these problems, the precision of the DYPP has been lowered to every 2nd multicolor pixel, and the maximum difference for the Y-position of each of these segments has been set to 1 pixel. So for each char, there is only 3 cases - up, straight or down.
 +The graphics has then been designed to be able to handle these cases without color clashes.
 +Storing the DYPP'ed gfx into FLI is done with some routines that have been specialized for each byte in the gfx, and for each DYPP case, so it can load it directly in immediate mode, without having to look it up in a table.
