/**
 * All glWindowPos commands go through here.
 * The (x,y,z) coordinate is in mural-space window coords.
 * We need to bias by the current tile's position.
 * Remember that the state differencer (used in the tilesort SPU) uses
 * glWindowPos to update the raster position on the servers, so that takes
 * care of proper position for tilesorting.
 * Also, this helps with sort-last rendering: if images are being sent to a
 * server that has tiles, the images will be correctly positioned too.
 * This also solves Eric Mueller's "tilesort-->readback trouble" issue.
 *
 * glRasterPos commands will go through unmodified; they're transformed
 * by the modelview/projection matrix which is already modified per-tile.
