    I have removed several incorrect calls to _lookupProperties from
    fl_BlockLayout; I suspect these might have been put there to fix
    some problems in the code at some point, but if so we need to fix
    the bug rather than the symptoms, _lookupProperties should only be
    called in response to a format change notification to our listeners.

    I have further added some extra logic to
    fp_TextRun::lookupProperties to avoid unnecessary clearScreen()
    calls, but it seems that my other changes have got rid of
    unnecessary calls to the function anyway.

    files: fl_BlockLayout.cpp, fp_Run.h/cpp, fp_TextRun.cpp
