3.3.5.8.4 MILCMD_GDISPRITEBITMAP_UNMAPSECTION

The MILCMD_GDISPRITEBITMAP_UNMAPSECTION packet indicates to the client that the sprite object referenced by this sprite resource MUST NOT be modified any further. This situation can arise, for example, if the server implements visual animations for a closing window.

During the closing animation, the server can stop sending graphical updates to the window's sprite. The client MUST NOT release the sprite object at this time, but it can, for example, perform certain storage optimizations that are advantageous only if the sprite is static. The client MAY ignore this message.
