PngCrunching now has a slightly better heuristic of choosing to encode
an image as a palette or RGB. For small images, RGB compresses much better
than a palette.
The original PNG is used as-is (minus some optional chunks being stripped)
if the resulting crunched PNG is larger than the original.
9-patch handling is abstracted away from PNGs, paving the way
for other 9-patches, like WebP.
TODO: handle PNGs with 9-patch chunks already present, which
should just be passed through. This will allow for 3rd party
tools to generate 9-patches.
TODO: implement cheap transparency: when one color is used to represent
transparent, and all other colors are opaque.

Configuration Split APK support: supports splitting resources that match a set of
configurations to a separate APK which can be loaded alongside the base APK on
API 21+ devices. This is done using the flag
--split path/to/split.apk:<config1>[,<config2>,...].
SDK version resource filtering: Resources with an SDK version qualifier that is unreachable
at runtime due to the minimum SDK level declared by the AndroidManifest.xml are stripped.
Version 2.0
aapt2 compile ...
Pseudo-localization: generates pseudolocalized versions of default strings when the
--pseudo-localize option is specified.
Legacy mode: treats some class of errors as warnings in order to be more compatible
with AAPT when --legacy is specified.
Compile directory: treats the input file as a directory when --dir is
specified. This will emit a zip of compiled files, one for each file in the directory.
The directory must follow the Android resource directory structure
(res/values-[qualifiers]/file.ext).
aapt2 link ...
Automatic attribute versioning: adds version qualifiers to resources that use attributes
introduced in a later SDK level. This can be disabled with --no-auto-version.
Min SDK resource filtering: removes resources that can't possibly be selected at runtime due
to the application's minimum supported SDK level.
