/// 2. Else if asset successfully loads, try to draw it by passing any PvIconAttributes through registry.
/// 3. Else check if asset path matches regex, and draw replacement if it does.
/// 4. Else check if asset extension matches one of the registered extns, and draw replacement if it does
/// 5. Failed to find a good substitute icon. Leave original icon intact.
