Visits an annotation on a type in the class signature.

@param typeRef
a reference to the annotated type. The sort of this type
reference must be {@link TypeReference#CLASS_TYPE_PARAMETER
CLASS_TYPE_PARAMETER},
{@link TypeReference#CLASS_TYPE_PARAMETER_BOUND
CLASS_TYPE_PARAMETER_BOUND} or
{@link TypeReference#CLASS_EXTENDS CLASS_EXTENDS}. See
{@link TypeReference}.
@param typePath
the path to the annotated type argument, wildcard bound, array
element type, or static inner type within 'typeRef'. May be
<tt>null</tt> if the annotation targets 'typeRef' as a whole.
@param desc
the class descriptor of the annotation class.
@param visible
<tt>true</tt> if the annotation is visible at runtime.
@return a visitor to visit the annotation values, or <tt>null</tt> if
this visitor is not interested in visiting this annotation.
