; Cursor data structure passed to OEM routines. Defines a graphics display*
|
|
; cursor in terms of a hotspot, an AND mask and an XOR mask. The hot *
|
|
; spot defines the pixel within the cursor that is the cursor is "pointing"*
|
|
; to. So when displaying a cursor at location X,Y the pixel that *
|
|
; is the hot spot should be painted at that X,Y coordinate. The "shape" *
|
|
; of the cursor is defined by two pixel masks. The first mask is ANDed *
|
|
; with the bits in the display bitmap and the second mask is XORed with *
|
|
; the result to determine the bits that will be placed in the display *
|
|
; bitmap. The bits for the masks are in the byte array that begins *
|
|
; at the csBits field, with the AND mask bits first, followed by the *
|
|
; XOR mask bits. The csWidthBytes field is the width of ONE mask, in *
|
|
; bytes. Currently, MS-WIN will only generate cursors whose width and *
|
|
; height are both 16. *
