WIN platform: implement Fl_GDI_Graphics_Driver::draw_scaled(Fl_Image *img,int,int,int,int) when img is a Fl_RGB_Image
Implementation uses StretchBlt() when img->d() is 1 or 3 and AlphaBlend() when it is 2 or 4.
This should turn useful to draw images on HighDPI displays using the display's true resolution.
