Eric Fischer	241d96e57c	Save a few more bytes per geometry in the temporary file ... by using bytes instead of ints for the drawing operations	2014-11-05 14:37:54 -08:00
Eric Fischer	c24cfada61	Move feature type to index so point skipping can avoid looking up geometry ... Which should avoid having to page the geometry in if there is more data than will fit in memory	2014-11-05 12:18:03 -08:00
