void GR_Win32USPGraphics::setFont ( const GR_Font *  pFont  )  [virtual]

The USP library maintains an internal font cache, which allows it to avoid accessing the DC for things like measuring fonts, etc. This means that often it is not necessary to have the font selected into the DC, and as SelectObject() is very time consuming, we will not be calling it from here at all, instead, we will only note which font is being set and call SelectObject() from inside the functions that access the DC only if that is necessary.
