objects. But, it cannot remove the line of line and arc.
When strokeColor(), strokeWidth(), fillColor() are called.
They will apply to all lines subsequently used, unless functions
noStrokeColor(), strokeWidth(), noFill() are called to change them.

__declspec(global) in Ch space.
Ch_DeclareFunc() declares a function with the system scope of
__declspec(global) in Ch space which call a C function in the binary space.
Ch_SetGlobalUserData() sets the global user data. It is useful when
multi Embedded Ch engines are invoked.
