Yes, until we hear otherwise it seems to me the best solution to the
Bing logo license problem.

I've cleaned up the patch a little and added DEP3 headers for inclusion
in the jmapviewer package. When the patch is forwarded upstream we have
a nice opportunity to get the upstream point of view on this issue.

Kind Regards,

Description: Download the Bing logo when it's not installed.
 The Bing logo is required for attribution when using the imagery, but the
 license terms covering the image are unclear. JMapViewer is licesed under
 the GPL, but the Bing logo is mostly likely not.
 To not require the inclusion of the bing_maps.png file in the jmapviewer
 package, the image is downloaded using the URL provided in the BrandLogoUri
 attribute of the attribution response.
