+ * The dxydxy parameters of the inverse transform determine how
+ * quickly we step through the source image.  For tiny scale
+ * factors (on the order of 1E-16 or so) the stepping distances
+ * are huge.  The image has been scaled so small that stepping
+ * a single pixel in device space moves the sampling point by
+ * billions (or more) pixels in the source image space.  These
+ * huge stepping values can overflow the whole part of the longs
+ * we use for the fixed point stepping equations and so we need
+ * a more robust solution.  We could simply iterate over every
+ * device pixel, use the inverse transform to transform it back
+ * into the source image coordinate system and then test it for
+ * being in range and sample pixel-by-pixel, but that is quite
+ * a bit more expensive.  Fortunately, if the scale factors are
+ * so tiny that we overflow our long values then the number of
+ * pixels we are planning to visit should be very tiny.  The only
+ * exception to that rule is if the scale factor along one
+ * dimension is tiny (creating the huge stepping values), and
+ * the scale factor along the other dimension is fairly regular
+ * or an up-scale.  In that case we have a lot of pixels along
+ * the direction of the larger axis to sample, but few along the
+ * smaller axis.  Though, pessimally, with an added shear factor
+ * such a linearly tiny image could have bounds that cover a large
+ * number of pixels.  Such odd transformations should be very
+ * rare and the absolute limit on calculations would involve a
+ * single reverse transform of every pixel in the output image
+ * which is not fast, but it should not cause an undue stall
+ * of the rendering software.
+ *
+ * The specific test we will use is to calculate the inverse
+ * transformed values of every corner of the destination bounds
+ * (in order to be user-clip independent) and if we can
+ * perform a fixed-point-long inverse transform of all of
+ * those points without overflowing we will use the fast
+ * fixed point algorithm.  Otherwise we will use the safe
+ * per-pixel transform algorithm.
+ * The 4 corners are 0,0, 0,dsth, dstw,0, dstw,dsth
+ * Transformed they are:
