Please download an example using a TiledMapSource and the OSGB1936Projection (setting it in OSGBTileProvider) here: https://dl.dropboxusercontent.com/u/1738032/RadMapMbtilesDemo.zip.
The following isn't working as expected:
* Center point conersion using the OSGB36Converter isn't correctly setting the center point
* Zooming in will not render tiles/not render them at the correct position.
Can you please tell us if we've got anything wrong/if there's a fix we need to download.
