    13 // Description:

    14 // Test alpha channel transparent windows

    15 // Test that draw operations with non-opaque colours do alpha blending in EColor64K and EColor16MA display modes

    16 // Test that alpha channel transparent windows are drawn correctly when windows move, redraw, change visibility, etc.

    17 // In the draw operation tests, the left window draws opaque pink on white background, the right window blends semi-transparent red on white background,

    18 // and the results are compared.

    19 // In the transparent window tests, the right window contains several transparent windows, which are moved, redrawn, visibility changed, etc,

    20 // the left window contains a single window in which we draw what we expect the right window to look like. The results are compared.

    21 // In each case, the left and right windows should be identical

    22 //
