-"fixed" warning about vars being used uninitialized (may happen if mouse cursor is totally offscreen or screen resolution is 0 pixel height, that is, never).

Browse Source 
-Put some cursor drawing loops in the right order (loop on y, then on x) to make them a little more cache-friendly (and easier to read). I wrote them the wrong way, sorry!
-Some code formatting to 80 columns (not really important, don't worry about it)
-Added a sample neochrome picture to the pic-samples folder.
