  * Example of a bitmap that covers some of the area from cell A1 to cell B2.
  *
  * Based on the width and height of the bitmap we need to calculate 8 vars:
  *	 $col_start, $row_start, $col_end, $row_end, $x1, $y1, $x2, $y2.
  * The width and height of the cells are also variable and have to be taken into
  * account.
  * The values of $col_start and $row_start are passed in from the calling
  * function. The values of $col_end and $row_end are calculated by subtracting
  * the width and height of the bitmap from the width and height of the
  * underlying cells.
  * The vertices are expressed as a percentage of the underlying cell width as
  * follows (rhs values are in pixels):
  *
  *	   x1 = X / W *1024
  *	   y1 = Y / H *256
  *	   x2 = (X-1) / W *1024
  *	   y2 = (Y-1) / H *256
  *
  *	   Where:  X is distance from the left side of the underlying cell
  *			   Y is distance from the top of the underlying cell
  *			   W is the width of the cell
  *			   H is the height of the cell
  * The SDK incorrectly states that the height should be expressed as a
  *		percentage of 1024.
  *
