GDK_INTERP_HYPER scale mode

[Andrey Tsyvarev <tsyvarev ispras ru>]

Hello,

The following is written in the documentation of GdkPixbuf as a
comment to GDK_INTERP_HYPER scale mode:

This is the slowest and highest quality reconstruction function.
It is derived from the hyperbolic filters in Wolberg's "Digital Image Warping",
and is formally defined as the hyperbolic-filter sampling the ideal hyperbolic-filter interpolated image
(the filter is designed to be idempotent for 1:1 pixel mapping).

Does it mean that the image shouldn't change when scaled with 'scale_x'
and 'scale_y' equal to 1.0?
