29     read pixels from memory, applications that use grids of tiles of pixels, 
33     break the image into a grid of rectangular tiles of pixels. Such an
39     of pixels. The grid of tiles is essentially a sequence of the structures
42     through the tiles, either coalescing the tiles into a single tile in
48     that use tiles of pixels and convolution must copy the subimage to be 
49     transferred from the grid of tiles to a contiguous region, then pass the

57     grid of tiles of pixels in addition to the current sequence of rows 
87       tiles of pixels are used; significant amounts of time are spent

239     consists of a series of rows of rectangular tiles. See Figure 3.8.a???.

253     establish the row of tiles in the grid containing the row of groups in

274     When transferring a subimage from the grid of tiles, a complete row of
