/**
* The maximum value of a coordinate in the internal tile coordinate system. Coordinates of
* all source features normalized to this extent upon load.
*
* The value is a consequence of the following:
*
* * Vertex buffer store positions as signed 16 bit integers.
* * One bit is lost for signedness to support tile buffers.
* * One bit is lost because the line vertex buffer used to pack 1 bit of other data into the int.
* * One bit is lost to support features extending past the extent on the right edge of the tile.
* * This leaves us with 2^13 = 8192
