 When multiple driver are available, GDAL uses the first successful driver.
 It is possible to deactivate drivers so I see a couple of
 options/enhancements

 --When building the supported file list, put the names into a
 QMap<extension, description>, then only the first driver (which GDAL will
 use) will be displayed, this will also allow for the list to be sorted by
 extension so that it is more user friendly

 --Add a raster driver tab to the "Settings->option" menu. This displays
 all possible drivers and the user can check which drivers to use (default
 to all on). Save these settings as QSettings

 --QgsRasterLayer::registerGdalDrivers() will need to check the QSettings
 to see if the driver is listed for inclusion/exclusion, defaults to
 include

 --Also means the supported file list will have to be generated each time
 the open dialog is open rather than once on initial load.

 That should generally meet most of the needs/requests. Would be good to
 get Frank's opinion on this.
