v1.3.0-beta.1

Changes since the last prerelease:

• GEGL builds fixed.
• Better organization of config.h vs. the public mypaint-config.h.

The only artefact here on github is the signed source. Binary and development packages may be available for your favourite OS already, and we maintain from-source builds for a few others. See the wiki's Packaging page for details of how to get libmypaint besides here. If you maintain such a package yourself, we'd love to have it listed.
