Detailed Description

off-screen resource defined as ref-counting, can refer one resource

Load a bitmap into a graphics:

*  nana::paint::graphics graph;
*  nana::paint::image img("C:\\ABitmap.bmp");
*  img.paste(graph, 0, 0); //graph may create if it is empty
*  

Examples:: a_group_impl.cpp, background-effects.cpp, categ.cpp, draw.cpp, and stretch_image.cpp.
