wl-mirror v0.16.0

This release finally adds fractional scaling support to wl-mirror, as well as adding a --scaling cover option for cropping the mirrored image to fit.

New Features

• Implemented fractional scale support
• Made scaling and scaling filter options independent (a scaling mode like --scaling exact and a scaling filter like --scaling linear or --scaling nearest can be applied simultaneously)
• Added --scaling cover option for cropping the mirrored image to fit
• Changed --scaling exact to also perform exact multiple downscaling
