53 * Class for processing all of the leaf fields of an uniform
55 * Leaves are, roughly speaking, the parts of the uniform that the application

57 * \c glGetActiveUniforms).
59 * Classes my derive from this class to implement specific functionality.
60 * This class only provides the mechanism to iterate over the leaves. Derived
61 * classes must implement \c ::visit_field and may override \c ::process.

73 * Calls \c ::visit_field for each leaf of the uniform.
