Currently BMP installs its icon in /usr/share/icons, which is going to be useful to no one. The ebuild installs the icon also on /usr/share/pixmaps, but also there its not completely standard. The attached patch applied over ebuild, with the other patch for bmp, put the icon in /usr/share/icons/hicolor/scalable/apps, where .svg icons should stay, and changes the .desktop file to not insert the .svg extension (so that icon themes could provide a new different icon for it).

In portage as 0.9.7-r3, done slightly different as I don't like to remove files in the install stage. If the file in /usr/share/icons really bothers you, please file a bug upstream. Thank you for your report.
