-/* Outline:
-*
-* we select a y-stretching function depending on the ratio (eg 1:N or N:1).
-* it copies scanlines from source to destination, duplicating or omitting
-* scanlines as necessary to fit the destination. It copies each scanline
-* via the X_FUNC function we passed as an argument: this copies one scanline
-* duplicating or omitting pixels to fit the destination: we select an X_FUNC
-* depending on the bit-depth as well as the x-stretching ratio.
-*
-* both x and y stretching functions use the following basic model for deciding
-* when to insert/omit elements:
-*
-* delta = <larger extent> -1;
-*
-* for (number of destination elements) {
-*
-* copy one element
-* advance pointer to larger region
-* delta -= <smaller extent>
-* if (delta < 0) {
-* delta += <larger extent>;
-* advance pointer to smaller region
-* }

-* an X_FUNC is a function that copies one scanline, stretching or shrinking it

-* bitdepth and stretch ratio (1:1, 1:2, 1:4, 1:N, N:1, 4:1, 2:1)

-* the x_fract argument is the delta fraction: it is a representation
-* of the smaller extent (whichever that is) as a fraction of the larger,
-* and is used when stretching or shrinking to advance the pointer to the
-* smaller scanline every (fract) pixels of the larger.
-* Thus if we are expanding 1:8, x_fract will be 1/8, we will advance the
-* source pointer once every 8 pixels, and thus copy each source pixel to
-* 8 dest pixels. Note that if shrinking 8:1, x_fract will still be 1/8
-* and we will use it to control advancement of the dest pointer.
-* the fraction is multiplied by 65536.
