flType
ulContent
- Can be one of:
RFONT_CONTENT_METRICS RFONT_CONTENT_BITMAPS RFONT_CONTENT_PATHS
hdevProducer
- HDEV of the font device that loaded this font. Identical to the hdev member of the correspinding PFF.
bDeviceFont
- TRUE if the font is a device font.
hdevConsumer
- HDEV of the device that uses this RFONT to output text.
dhpdev
- Driver defined device handle, that identifies the output device identified by hdevConsumer.
