New description:

 To get a much better performance on every ST_Get function on the raster
 header:

 RASTER_convex_hull[[BR]]
 RASTER_getSRID[[BR]]
 RASTER_getWidth[[BR]]
 RASTER_getHeight[[BR]]
 RASTER_getNumBands[[BR]]
 RASTER_getXScale[[BR]]
 RASTER_getYScale[[BR]]
 RASTER_setScale[[BR]]
 RASTER_setScaleXY[[BR]]
 RASTER_getXSkew[[BR]]
 RASTER_getYSkew[[BR]]
 RASTER_setSkew[[BR]]
 RASTER_setSkewXY[[BR]]
 RASTER_getXUpperLeft[[BR]]
 RASTER_getYUpperLeft[[BR]]
 RASTER_setUpperLeftXY

 See if it is possible to do the same for a requested band so we can
 improve the performance of every other functions.
