WinBrush : Brush for filling geometries
WinPen : Pen for filling lines
WinFont : Font
WinDC : Device Context
WinControlDC : Device Context from HWND
WinImageDC : Device Context from images

Comments:
WinDC::PolyDraw
Points : Points
Actions : How to deal with points
PT_MOVETO ：MoveTo and consume 1 point
PT_LINETO ：LineTo and consume 1 point
PT_BEZIERTO ：Draw a bezier curve and consume 3 points
PT_LINETO and PT_BEZIERTO can be mixed with PT_CLOSFIGURE to close the geometry begins from the last PT_MOVETO that happened

TransformAlphaChannel()： Convert to an GDI compatible bitmap with alpha channel after all pixels are filled.
Generate×××()： Predefined alpha channel generation, TransformAlphaChannel should be called after that
