openGLExtension [-extension string] [-renderer] [-vendor] [-version]
openGLExtension is NOT undoable, NOT queryable, and NOT editable.
Command returns the extension name depending on whether a given
OpenGL extension is supported or not. The input is the
extension string to the -extension flag.
If the -extension flag is not used, or if
the string argument to this flag is an empty string
than all extension names are returned in a single string.
If the extension exists it is not necessary true that
the extension is supported.
This command can only be used when a modeling
view has been created. Otherwise no extensions
will have been initialized and the resulting
string will always be the empty string.
