The parameters for these methods are very similar. Both scale() and
composite() creates a transformation of the source image by scaling
by $scale_x and $scale_y then translating by $offset_x and
$offset_y, then rendering the rectangle ($dest_x, $dest_y,
$dest_width, $dest_height) of the resulting image onto the
destination image replacing the previous contents. The composite()
method has an additional $overall_alpha parameter specifying the
transparency of the source image when it's composited.
The composite_color() is one monster method that can be used to
replace all the methods seen so far.
