Ah, this could be the cause of 9512 over which I have lost lot of sleep
:). On win32 the printer graphics and the screen graphics have different
resolutions and cannot, therefore, share a common cache.

Such method is much needed; the fp_EmbedRun::updateVerticalMetric() and
::_recalcWidth() (which are currently only called from the win32 build,
but are necessary) at the moment has to delete the embedded object and
recreate it, which as luca notes is costly.
