[mapguide-internals] Raster Quality and Stability - RFC and Funding

[Zac Spitzer]

Hi list,

in order to proceed with this work, we need the community to donate some
money towards this project. The last round of Raster improvements was funded
by 5 companies as listed on the project page, OTX systems isn't directly
listed, but Trevor ( it's his company) did the actual work and as a result
we have a working stable raster implementation.

http://www.otxsystems.com/community-initiatives/gdal-provider-initiative.html

There are a lot of companies out there using MapGuide, so this is a call out
to all the MapGuide users, so who would like to donate towards this initiative?

The target amount is 13,345.15 USD or 9,243.33 EUR, this can be easily
achieved if 20 or 30 individual consultants or companies pitch in.

Feel free to reply to the list, or if you would like to pledge a
donation privately,
I suggest emailing Trevor directly.

Regards

Zac

I will write more details into the FDO and MapGuide RFCs if we can get sufficient sponsorship funding for the project.
