3.3.5.1.2.1.5 Construction of Cache Glyph (Revision 2)
The structure and fields of the Cache Glyph (Revision 2) Secondary Drawing Order are specified in section 2.2.2.2.1.2.6. The order fields MUST be populated in accordance with this description.
The construction of the Cache Glyph (Revision 2) Order follows the same principles as those outlined for the Cache Glyph (Revision 1) Order specified in section 3.3.5.1.2.1.4. However, the Cache Glyph (Revision 2) Order utilizes a more efficient field encoding.
The Cache Glyph (Revision 2) Order MUST NOT be sent to the client if support for Revision 2 glyph caching was not specified using the Glyph Cache Capability Set (see [MS-RDPBCGR] section 2.2.7.1.8). Furthermore, if client-side support for the GlyphIndex, FastIndex, and FastGlyph Primary Drawing Orders (specified using the Order Capability Set specified in [MS-RDPBCGR] section 2.2.7.1.3) does not exist, the Cache Glyph (Revision 2) Order SHOULD NOT be sent to the client.
