text/html and application/x-pdf FORMATS and WMS GetLegendGraphic and WMS GetCapabilities

[Havard Tveite]

Bart,
The behaviour you have observed (returning png no matter what
FORMAT is specified) was a bug, and was fixed some days ago.
Using the latest CVS or the 4.4 beta2, one should get the
specified format.

I thought OUTPUTFORMAT was only for raster. Is it not?
