* The hardware cursor definition requires 2 bits per pixel. The
* Cursor size reguardless of the visible cursor size is 64 pixels
* by 64 lines. The total memory required to define the cursor is
* 16 bytes / line for 64 lines or 1024 bytes of data. The data
* must be in a contigiuos format. The 2 bit cursor code values are
* as follows:
*
* 00 - pixel colour = CURSOR_CLR_0
* 01 - pixel colour = CURSOR_CLR_1
* 10 - pixel colour = transparent (current display pixel)
* 11 - pixel colour = 1's complement of current display pixel
*
* Cursor Offset 64 pixels Actual Displayed Area
* \_________________________/
* | | | |
* |<--------------->| | |
* | CURS_HORZ_OFFSET| | |
* | |_______| | 64 Lines
* | ^ | |
* | | | |
* | CURS_VERT_OFFSET| |
* | | | |
* |____________________|____| |
*
*
* The Screen position of the top left corner of the displayed
* cursor is specificed by CURS_HORZ_VERT_POSN. Care must be taken
* when the cursor hot spot is not the top left corner and the
* physical cursor position becomes negative. It will be be displayed
* if either the horizontal or vertical cursor position is negative
*
* If x becomes negative the cursor manager must adjust the CURS_HORZ_OFFSET
* to a larger number and saturate CUR_HORZ_POSN to zero.
*
* if Y becomes negative, CUR_VERT_OFFSET must be adjusted to a larger number,
* CUR_OFFSET must be adjusted to a point to the appropraite line in the cursor
* definitation and CUR_VERT_POSN must be saturated to zero.
