PopupMenuSettings::scrollZone

Feature Requests
1

I would like to change the size of the scroll Up/Down arrow buttons inside a PopupMenu, and it looks like that is hardcoded to 24 at the top of juce_PopupMenu.cpp:

namespace PopupMenuSettings
{
    const int scrollZone = 24;
    const int dismissCommandId = 0x6287345f;

    static bool menuWasHiddenBecauseOfAppChange = false;
}

So it seems that I need to change the JUCE library code to pull this off, which is less than ideal.

Is there a way to do this in a LookAndFeel? Or, if not, could it be added?
