    Summary:
    Tests the PostFX Gradient Weight Modifier component can be added to an entity and has the expected functionality.

    Test setup:
    - Wait for Editor idle loop.
    - Open the "Base" level.

    Expected Behavior:
    The component can be added, used in game mode, hidden/shown, deleted, and has accurate required components.
    Creation and deletion undo/redo should also work.

    Test Steps:
    1) Create a PostFX Gradient Weight Modifier entity with no components.
    2) Add a PostFX Gradient Weight Modifier component to PostFX Gradient Weight Modifier entity.
    3) Remove PostFX Gradient Weight Modifier component.
    4) UNDO component removal.
    5) Verify PostFX Gradient Weight Modifier component not enabled.
    6) Add PostFX Layer component since it is required by the PostFX Gradient Weight Modifier component.
    7) Verify PostFX Gradient Weight Modifier component is enabled.
    8) Set 'Gradient Entity Id' property
    9) Set 'Opacity' property
    10) Toggle 'Invert Input' property
    11) Toggle 'Enable Levels' property
    12) Set 'Input Max' property
    13) Set 'Input Min' property
    14) Set 'Input Mid' property
    15) Set 'Output Max' property
    16) Set 'Output Min' property
    17) Toggle 'Enable Transform' property
    18) Set 'Scale' property
    19) Set 'Rotate' property
    20) Set 'Translate' property
    21) Enter/Exit game mode.
    22) Test IsHidden.
    23) Test IsVisible.
    24) Delete PostFX Gradient Weight Modifier entity.
    25) UNDO deletion.
    26) REDO deletion.
    27) Look for errors.
