+ /* We are dealing with 5 coordinate spaces in this function. this makes
+ * it ugly.
+ *
+ * - "Image" space is the space of the surface we're reading pixels from.
+ * it is the surface argument to this function. The surface has a
+ * matrix attached to it which maps "user" space (see below) into
+ * image space.
+ *
+ * - "Device" space is the space of the surface we're ultimately writing
+ * pixels to. It is the current surface of the gstate argument to
+ * this function.
+ *
+ * - "User" space is an arbitrary space defined by the user, defined
+ * implicitly by the gstate's CTM. The CTM maps from user space to
+ * device space. The CTM inverse (which is also kept at all times)
+ * maps from device space to user space.
+ *
+ * - "Clip" space is the space of the surface being used to clip pixels
+ * during compositing. Space-wise, it is a bounding box (offset+size)
+ * within device space. This surface is usually smaller than the device
+ * surface (and possibly the image surface too) and logically occupies
+ * a bounding box around the "clip path", situated somewhere in device
+ * space. The clip path is already painted on the clip surface.
+ *
+ * - "Pattern" space is another arbitrary space defined in the pattern
+ * element of gstate. As pixels are read from image space, they are
+ * combined with pixels being read from pattern space and pixels
+ * already existing in device space. User coordinates are converted
+ * to pattern space, similarly, using a matrix attached to the pattern.
+ * (in fact, there is a 6th space in here, which is the space of the
+ * surface acting as a source for the pattern)
+ *
+ * To composite these spaces, we temporarily change the image surface
+ * so that it can be read and written in device coordinates; in a sense
+ * this makes it "spatially compatible" with the clip and device spaces.
+ *
+ *
+ * There is also some confusion about the interaction between a clip and
+ * a pattern; it is assumed that in this "show surface" operation a pattern
+ * is to be used as an auxiliary alpha mask. this might be wrong, but it's
+ * what we're doing now.
+ *
+ * so, to follow the operations below, remember that in the compositing
+ * model, each operation is always of the form ((src IN mask) OP dst).
+ * that's the basic operation.
+ *
+ * so the compositing we are trying to do here, in general, involves 2
+ * steps, going via a temporary surface:
+ *
+ * - combining clip and pattern pixels together into a mask channel.
+ * this will be ((pattern IN clip) SRC temporary). it ignores the
+ * pixels already in the temporary, overwriting it with the
+ * pattern, clipped to the clip mask.
+ *
+ * - combining temporary and "image" pixels with "device" pixels,
+ * with a user-provided porter/duff operator. this will be
+ * ((image IN temporary) OP device).
+ *
+ * if there is no clip, the degenerate case is just the second step
+ * with pattern standing in for temporary.
