2D PNG Image class.

The PM2DImage class accesses and manages PNG bitmap resources through reference-counting. Reference-counting allows the system to use one bitmap in multiple places. The library maintains the lifetime of this bitmap until all users are finished with it.

You can construct, destruct, copy, and assign objects of this class.

Constructs the bitmap image object.

Load a bitmap image from the specified resource library with its specified bitmap identifier. If you have not already loaded the bitmap and you want load it from the default resource library, use this constructor.

Params:

x	Horizontal position of the bitmap.
y	Vertical position of the bitmap.
res_id	The identifier of the bitmap.
hmodule	Module handle referencing a dynamic link library containing the resource or NULLHANDLE for the application's module.
