Precedence - Searching for TV_ttf_display_type
Only one call to a TV_ttf_display_type will be attempted per object to be displayed, even if multiple candidates are defined. For a type T, TotalView will look for the function in this order:
1 A class-qualified class (static) function returning int and taking a single const T * as its only argument.
2 A function at file scope, returning int and taking a single const T * as its only argument.
3 A global function, returning int and taking a single const T * as its only argument.
4 A TCL transformation
Namespace qualifications are not directly considered.
