Btw, speaking about cursors, I've also found an oddity, which affects 
all the supported platforms:
I think that if SDL emulates the cursor (so, uses SW cursor), and the 
video surface is a HWSURFACE, then SDL_UpdateRects() will not draw the 
cursor, because that branch of the 'if' has no logic to handle SW cursor.

Also a problem is that if the user blits directly into the screen 
surface (HW surface, again) using SDL_UpperBlit(), then SW cursor can be 
overwritten/deleted, there is no logic to handle that.

I don't know if these are known problems, just thought that I may note it.
