Graphic window width divided by 16. Holds graphic window x-axis size, divided by 16. For black-and-white panels (1
GW_XMAX
bpp), GW_XMAX[0] is ignored, forcing the x-axis of the screen size to be a multiple of 32 pixels/line. The graphic
window size cannot be set to 0.
Note: The maximum supported panel size is 800x600 pixels. Therefore the maximum value for this bit field is 0x32.

Graphic window height. Specifies the height of the graphic window in terms of pixels or lines. The lines are numbered
GW_YMAX
from 1 to GW_YMAX for a total of GW_YMAX lines. The graphic window size cannot be set to 0.
Note: The maximum supported panel size is 800x600 pixels. Therefore the maximum value for this bit field is 0x258.

represent the number of 32-bit longwords required to hold the data for one virtual line. GWVPW is used in
calculating the starting address representing the beginning of each line of the graphic window picture.
