* | Info        :
* -----------------------------------------------------------------------------
* V3.1(2019-10-10):
* 1. Add gray level
*   PAINT Add Scale
* 2. Add void Paint_SetScale(UBYTE scale);
* 
* V3.0(2019-04-18):
* 1.Change: 
*    Paint_DrawPoint(..., DOT_STYLE DOT_STYLE)
* => Paint_DrawPoint(..., DOT_STYLE Dot_Style)
*    Paint_DrawLine(..., LINE_STYLE Line_Style, DOT_PIXEL Dot_Pixel)
* => Paint_DrawLine(..., DOT_PIXEL Line_width, LINE_STYLE Line_Style)
*    Paint_DrawRectangle(..., DRAW_FILL Filled, DOT_PIXEL Dot_Pixel)
* => Paint_DrawRectangle(..., DOT_PIXEL Line_width, DRAW_FILL Draw_Fill)
*    Paint_DrawCircle(..., DRAW_FILL Draw_Fill, DOT_PIXEL Dot_Pixel)
* => Paint_DrawCircle(..., DOT_PIXEL Line_width, DRAW_FILL Draw_Filll)
*
* -----------------------------------------------------------------------------
* V2.0(2018-11-15):
* 1.add: Paint_NewImage()
*    Create an image's properties
