[Qgis-psc] Nomination of commit rights for Mathieu Pellerin

[Nyall Dawson]

Hi PSC,

I'd like to nominate Mathieu Pellerin ("@nirvn") for commit rights to
the QGIS repository.

As https://github.com/qgis/QGIS/graphs/contributors shows, Mathieu is
currently our 25th most active committer, and he has a longstanding
history with the project. He's a great asset to the project, with
skills in UX and visual design, he has a great comprehension of the
needs of power QGIS users, and he's shown a thorough understanding of
the "bigger picture" when it comes to designing features and fixes for
QGIS.

I've found Mathieu's work to be of a very high quality, and I am
always confident that any changes he submits have been extensively
tested and well considered. He's always quick to respond to
suggestions and follow up his work with bug fixes.

I would like to nominate Mathieu for two roles:
1. maintenance of QGIS visual assets. The bulk of Mathieu's work to
date has centered on adding polish to QGIS' user interface and
standardising and improving our icon set. Here's an example of the
kind of very welcome changes Mathieu has made:
https://github.com/qgis/QGIS/pull/2088
https://github.com/qgis/QGIS/pull/2766
https://github.com/qgis/QGIS/pull/2799
This kind of attention to detail has really helped make recent QGIS
releases look much more like a professional project vs an open-source
hobby project.
2. UI polish and bugfixes.

(While Mathieu has also submitted valuable, high quality features to
composer, processing, etc I believe these kinds of changes are best
served through the PR process (as is common practice by core
developers for almost all larger changes now!).)

Lastly, I believe Mathieu is a perfect example of a QGIS community
member. His initial contributions consisted of high quality bug
reports and feature requests, and as his involvement and skills have
improved he's progressed through to confidence in tackling tricky c++
changes. I consider Mathieu to be a great reflection of how well the
QGIS community can handle mentoring new contributors and developing
their skills and how well this initial investment pays off in the long
run.

In short, I'd love to see Mathieu granted core access so that he can
push his contributions faster and also as recognition of his years of
quality contributions to the project!
