Int 33 Fn 0009 - MS Mouse V3.0+ - Define Graphics Cursor [M]
AX = 0009h
BX = column of cursor hot spot in bitmap (-16 to 16)
CX = row of cursor hot spot (-16 to 16)
ES:DX -> bitmap
16 words screen mask
16 words cursor mask
each word defines the sixteen pixels of a row, low bit
rightmost
Notes: in graphics modes, the screen contents around the current mouse cursor
position are ANDed with the screen mask and then XORed with the
cursor mask
the Microsoft mouse driver v7.04 and v8.20 uses only BL and CL, so the
hot spot row/column should be limited to -128..127
Microsoft KnowledgeBase article Q19850 states that the high bit is
right-most, but that statement is contradicted by all other available
documentation
