fraction: (CGFloat)delta;
Availability: MacOS-X 10.0.0
Takes the part of the receiver given by
srcRect and draws it in
dstRect in the current
coordinate system, transforming the image as
necessary.
The image is drawn as if it was drawn to a cleared
window, then dissolved using the fraction
delta to another cleared
window, and finally composited using
op to the destination.
Note that compositing and dissolving doesn't work on
all devices (printers, in particular).

call this one
We only use caching on backends
that can efficiently draw a rect from the cache onto
the current graphics context respecting the CTM, which
is currently cairo.
