[Qgis-psc] Proposal to support multi-threaded development

[Andreas Neumann]

Hi PSC,

In October Peter and Saber proposed a project to work on the
multi-threaded rendering. The new Vector API (which was also co-funded
by the QGIS user group in Switzerland) was the preparation for this
follow-up work. The development work on the multi-threaded rendering
would be carried out by Martin Dobias.

Lutra Consulting, the current employer of Martin, is looking to raise
Euro 20k for this project. The QGIS user group pays CHF 3000.- this year
and will most likely pay a similar amount again next year.

I am asking the PSC that the international QGIS project is also
co-funding this project, perhaps with approx. Euro 5k.

Marco Hugentobler worked on multi-threaded rendering in QGIS enterprise
(based on the 1.9x branch). Horst demoed this version at the recent QGIS
CH coordination meeting. It looks very promising as it does not block
the UI. Users can navigate to a different extent while QGIS is still
rendering. QGIS would then cancel the old render threads and start with
the new threads. But this work is not compatible with the 2.x
development branch. However, it shows the potential of threaded rendering.

What is the opinion of the PSC? Can the international group co-fund this
initiative?

Andreas
