 140 > returns an double value
 141 to use with FC_WEIGHT, from an double in the 1..1000 range, resembling
 142 the numbers from OpenType specification's OS/2 usWeight numbers, which
 143 are also similar to CSS font-weight numbers.  If input is negative,
 144 zero, or greater than 1000, returns -1.  This function linearly interpolates
 145 between various FC_WEIGHT_* constants.  As such, the returned value does not
 146 necessarily match any of the predefined constants.
