I've finished my own trivial engine framework, by using CEGUI, I finished the GUI system, but there's a problem left, when I rendering a FrameWindow, problems occurs, it will come to SetScissorTest, which call Direct3D9 render system's D3DRS_SCISSORTESTENABLE,
<I get an error when set this render state, since clip rect have negative values, and I mark this scissor test code, it will render a FrameWindow without Titlebar displayed correctly, then I'm here, dears~~, waiting for your help!>
Thanks in advance!!!!!
