// There is a major hack going on in this method. The viewer doesn't request
// map blocks (RequestMapBlocks) above 2048. That means that if we don't hack,
// grids above that cell don't have a map at all. So, here's the hack: we wait
// for this CAP request to come, and we inject the map blocks at this point.
// In a normal scenario, this request simply sends back the MapLayer (the blue color).
// In the hacked scenario, it also sends the map blocks via UDP.
//
// 6/8/2011 -- I'm adding an explicit 2048 check, so that we never forget that there is
// a hack here, and so that regions below 4096 don't get spammed with unnecessary map blocks.
