Although we try to use official sources for dependencies, sometimes the official sources don't support a platform (especially mobile platforms), or there's a bug fix/feature that is required to support Pillow's usage.

This folder contains patches that must be applied to official sources, organized by the platforms that need those patches.

Each patch is against the root of the unpacked official tarball, and is named by appending .patch to the end of the tarball that is to be patched. This includes the full version number; so if the version is bumped, the patch will at a minimum require a filename change.

Wherever possible, these patches should be contributed upstream, in the hope that future Pillow versions won't need to maintain these patches.
