This method recursively subdivides the tile rendering problem

in smaller parts, i.e. rendering output size x with few tiles

of size y, which in turn are generated from the original
|
|
bitmap in a recursive fashion. The subdivision size can be

controlled by the exponent argument, which specifies the

|
minimal number of smaller tiles used in one recursion
|
|
step. The resulting tile size is given as the integer number
|
|
of repetitions of the original bitmap along x and y. As the
|
|
exponent need not necessarily divide these numbers without
|
|
remainder, the repetition counts are effectively converted to
|
|
base-exponent numbers, where each place denotes the number of
|
|
times the corresponding tile size is rendered.
