-// Description:
-// Test alpha channel transparent windows
-// Test that draw operations with non-opaque colours do alpha blending in EColor64K and EColor16MA display modes
-// Test that alpha channel transparent windows are drawn correctly when windows move, redraw, change visibility, etc.
-// In the draw operation tests, the left window draws opaque pink on white background, the right window blends semi-transparent red on white background,
-// and the results are compared.
-// In the transparent window tests, the right window contains several transparent windows, which are moved, redrawn, visibility changed, etc,
-// the left window contains a single window in which we draw what we expect the right window to look like. The results are compared.
-// In each case, the left and right windows should be identical
-//
