%description
Fast alternatives to several relatively slow 'raster' package functions.
For large rasters, the functions run from 5 to approximately 100 times
faster than the 'raster' package functions they replace. The 'fasterize'
package, on which one function in this package depends, includes an
implementation of the scan line algorithm attributed to Wylie et al.
(1967) <doi:10.1145/1465611.1465619>.
