188.8.131.52.1.1.15 Processing of FastGlyph
The structure and fields of the FastGlyph Primary Drawing Order are specified in section 184.108.40.206.220.127.116.11, and the techniques described in section 18.104.22.168.1.1 demonstrate how to decode and process the order.
If support for glyph caching was not specified in the Glyph Cache Capability Set (see [MS-RDPBCGR] section 22.214.171.124.8), the client SHOULD ignore this order because it requires the existence of the glyph caches (see section 126.96.36.199.2).
All of the glyphs associated with the glyph cache indices specified in the order MUST have been received by the client in a prior Revision 1 or 2 Cache Glyph Secondary Drawing Order (see sections 188.8.131.52.2.1.4 and 184.108.40.206.2.1.5) or a FastGlyph Primary Drawing Order.
Once the client has completed decoding and processing the FastGlyph order, and the glyph has been rendered successfully, the glyph data MUST be stored in the specified glyph cache.
