[Qgis-user] Problem with WMS 1.1.1 data providers in QGIS 2.0.1

[Jonathan Moules]

Looking at the specs briefly, it doesn't seem like the ability to set DPI
explicitly is specified in WMS 1.1.0 or 1.3.0.
I guess that MapServer can't handle stuff it's not expecting. Maybe a
config option as Richard suggests.
