Pixman is a library that provides low-level pixel manipulation
features such as image compositing and trapezoid rasterization.

Sending patches
---------------
Patches should be submitted in form of Merge Requests via Gitlab.
The general workflow for sending patches is to first make sure that
git can send mail on your system. Then,
You will first need to create a fork of the main pixman repository at
- create a branch off of master in your local git repository
https://gitlab.freedesktop.org/pixman/pixman
- make your changes as one or more commits
via the Fork button on the top right. Once that is done you can add your
personal repository as a remote to your local pixman development git checkout:
- use the
git remote add my-gitlab git@gitlab.freedesktop.org:YOURUSERNAME/pixman.git
git send-email
git fetch my-gitlab

Once that is set up, the general workflow for sending patches is to create a
new local branch with your improvements and once it's ready push it to your
personal pixman fork:
git checkout -b fix-some-bug
...
git push my-gitlab
The output of the `git push` command will include a link that allows you to
create a Merge Request against the official pixman repository.
Whenever you make changes to your branch (add new commits or fix up commits)
you push them back to your personal pixman fork:
git push -f my-gitlab
If there is an open Merge Request Gitlab will automatically pick up the
changes from your branch and pixman developers can review them anew.
