 In the current implementation of the wms client, there is no way to set a
 max width and height. Trying to access a server that limits requests to a
 max width and height fails when these values are too high. Apparently they
 are determined by the map window size, as downsizing this window makes the
 map appear.

 So, there are two problems here:

 1) No way to set max values other then by resizing window.

 2) If the window size is too large, the layer is simply not shown. What is
 weird in my test case [1] is that I see the map in its full extension, but
 when I try to zoom, the map window remains empty. Which is obviously an
 unexpected behaviour, unless you understand the whole issue of max sizes
 and how these are determined.

 So, this is somewhere between a bug (no error message explaining why the
 map doesn't show up) and an enhancement wish for the possibility of
 indicating max values.
