226	* Load the legacy VMSVGA3DCONTEXT from saved state version VGA_SAVEDSTATE_VERSION_VMSVGA_MIPLEVELS (23)
227	* or earlier, i.e. 6.1 or old trunk.
228	*
229	* The saved state incompatibility has been introduced in two revisions:
230	*
231	* - r140506: which makes sure that VMSVGA structures are tightly packed (pragma pack(1)).
232	* This caused all structures which have a member from VMSVGA headers (like VMSVGALIGHTSTATE) to be packed too.
233	* For example the size of aLightData element (VMSVGALIGHTSTATE) is 2 bytes smaller on trunk (118) than on 6.1 (120),
234	* which happens because SVGA3dLightData member offset is 2 on trunk and 4 on 6.1.
235	*
236	* - r141385: new VMSVGA device headers.
237	* SVGA3D_RS_MAX is 99 with new VMSVGA headers, but it was 100 with old headers.
238	* 6.1 always saved 100 entries; trunk before r141385 saved 100 entries; trunk at r141385 saves 99 entries.
239	*
240	* 6.1 saved state version is VGA_SAVEDSTATE_VERSION_VMSVGA_SCREENS (21).
241	* Trunk r141287 introduced VGA_SAVEDSTATE_VERSION_VMSVGA_MIPLEVELS (23).
242	*
243	* Both issues has been solved by loading a compatible context structure for saved state
244	* version < VGA_SAVEDSTATE_VERSION_VMSVGA_MIPLEVELS.
245	* This means that trunk will not be able to load states created from r140506 to r141385.
