35 * Virtual class implemented by each test to redirect static operation / state transitions to
36 * virtual methods.
37 *
38 * Virtual dispatch allows for default behaviors to be specified (very common case in below tests),
39 * and allows Renderer vs Dispatching behavior to be merged.
40 *
41 * onXXXOp methods fail by default - tests should override ops they expect
42 * startRepaintLayer fails by default - tests should override if expected
43 * startFrame/endFrame do nothing by default - tests should override to intercept
