    plug-ins: fix a type warning.
    
    Since obj->type_data is also int anyway, multiplying by a double value
    is unneeded anyway. So let's just make an integer multiplication.
    Fixes the following warning:
    > warning: using integer absolute value function ‘abs’ when argument is
    > of floating point type ‘double’ [-Wabsolute-value]
