@FUNC@ FcWeightFromOpenTypeDouble
@TYPE1@ double @ARG1@ ot_weight
@PURPOSE@ Convert from OpenType weight values to fontconfig ones
@DESC@
<function>FcWeightFromOpenTypeDouble</function> returns an double value
to use with FC_WEIGHT, from an double 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.
