Hi
I've been trying out 12-RC1 and have noticed that WMSLayer now has inferior
behavior compared to 11.1. 12-RC1 seems to ask the WMS with a different SRS
from what I ask for, and then transform the image on the client, where 11.1
just asks the WMS for the right SRS to begin with. Here is some code that can
demonstrate the suspected regression. You may have to zoom in one level to see
that the text that was horizontal with 11.1, is slanted with 12-RC, plus the
fact that the image quality is worse. The WMS I use may have some limits as to
how often it may be called.
