• add Imager::Test to the POD coverage tests and document the missing functions.

• the convert() method now optimizes the case where all output channels are either 0, sourced from a single input channel or 1. This significantly speeds up presets like "addalpha", "green". RT #51254

• add wiggle.pl sample, as suggested by Dan Oppenheim.

• add the combine() method to combine channels from multiple source images into a new image RT #11872

Bug fixes:

• treat the co-efficients for convert() as doubles instead of floats.

• If a higher (earlier) priority font handler failed to load, that would crash preventing loading of later font handlers. RT #62855

• parse defines from the options returned by pkg-config --cflags RT #63223

• a regen of the MANIFEST revealed that GIF and FT2 tests weren't included in the tarball. They are now included.
