6472ST-V VDP2 window effect function version 0.04
6473
6474How it works: returns 0 if the requested pixel is drawnable,1 if it isn't.
6475For tilemap and sprite layer, clipping rectangle is changed.
6476
6477Done:
6478-Basic support(w0 or w1),bitmaps only.
6479-W0 (outside) for tilemaps and sprite layer.
6480-Window logic.
6481
6482Not Done:
6483-Complete Windows on cells.A split between cells and bitmaps is in progress...
6484-w0 & w1 at the same time.
6485-Line window.
6486-Color Calculation.
6487-Rotation parameter Window (already done?).
6488
6489Window Registers are hooked up like this ATM:
6490    x--- ---- UNUSED
6491    -x-- ---- Sprite Window Area
6492    --x- ---- Window 1 Area
6493    ---x ---- Window 0 Area
6494                  (0 = Inside,1 = Outside)
6495    ---- x--- Sprite Window Enable
6496    ---- -x-- Window 1 Enable
6497    ---- --x- Window 0 Enable
6498                  (0 = Disabled,1 = Enabled)
6499    ---- ---x Window Logic
6500                  (0 = OR,1 = AND)
