Set this bit to activate the window shadowing. When the window is
active, the right M pixels and lower N horizontal scan lines will output
shadowing. The M, N, and color of window shadow is defined in the
frame control registers located at row 15, column 16, 17, 18, and 19.

These bits define the color of the background window.
These bits define the vertical starting position. The 8-bit gives 256
steps, with each step increment of four horizontal lines for each field.
Its value cannot be zero at anytime. In order to avoid screen
misalignment, the value of VERTD is decided by the last OSD line not
over the next leading edge of PVSYNC.
1 = Background window shadow enabled
0 = Background window shadow disabled
