@FUNC@		FcWeightFromOpenType

@PURPOSE@	Convert from OpenType weight values to fontconfig ones
@DESC@
<function>FcWeightFromOpenType</function> returns an integer value
to use with FC_WEIGHT, from an integer in the 1..1000 range, resembling
the numbers from OpenType specification's OS/2 usWeight numbers, which
are also similar to CSS font-weight numbers.  If input is negative,
zero, or greater than 1000, returns -1.  This function linearly interpolates
between various FC_WEIGHT_* constants.  As such, the returned value does not
necessarily match any of the predefined constants.
