Isn't both "i" and "255" should be propagated to
int before comparison?
Implicitly propagated, I mean.
Regardless, a ubyte 0 converted to an int is still 0.
a ubyte can only hold a maximum of 255 and will roll over to 0
when incremented at that point.
So,
i = 0
i <= 255 (0 <= 255 is true)
// do stuff
++i (i = 1)
i <= 255 (1 <= 255 is true)
// do stuff
...
++i (i = 255)
i <= 255 (255 <= 255 is true)
// do stuff
++i (i = 0)
i <= 255 (0 <= 255 is true)
... go on infinitely.
