[Qgis-developer] WMS enhancement request: possiblity to pass wmsprovider::draw a list of custom parameters

[G. Allegri]

We need to update a WMS layer with some additional custom parameters
during it's draw request.
I see that this is impossible, and ew have to make a new WMS instance
to do it, as all the wmsprovider parameters aren't updatable (uri,
etc.).
What about adding a fourth parameter to QgsWmsProvider::draw(
QgsRectangle  const &viewExtent, int pixelWidth, int pixelHeight ),
like a QMap<QString,QString>, to pass additional parameter to the
QNetworkRequest request?
