+// headers and libraries to be able to compile the library with wxUSE_GLCANVAS
+// set to 1. Note that for some compilers (notably Microsoft Visual C++) you
+// will need to manually add opengl32.lib and glu32.lib to the list of
+// libraries linked with your program if you use OpenGL.

+// Default is 0.
