2005-04-16 1101 * This reduces the number of times for access to draw the

2007-10-16 1104 * (total of 8192 bits or 1024 bytes). The two patterns are
2005-04-16 1105 * stored in such a way that pattern 0 always resides in the
2005-04-16 1106 * lower half (least significant 64 bits) of a 128 bit word

2005-04-16 1112 * (128 bits) which is the maximum cursor width times two for
2005-04-16 1113 * the two monochrome patterns.
