GfxState: SurfaceStore (slot->{resId,colorkey} from create/set-texture) + object
SourceSlot/SrcRect/Visible (from draw-texture bind); SnapshotVisibleObjects returns
visible objects in ascending-handle order (=z-order) with their live surface resolved.
VM set/create/draw-texture wired to it. Oracle dumps visible objects. Erase removes the
object from the registry (faithful). Engine 44 green.

0x202/0x203 pack (alpha,color) via GfxState.PackColor onto the object; the actual
alpha/additive blend is deferred and surfaced once through the trace sink (observe-
only, parity held). Full suite 37 green.

Gfx property on VirtualMachine + dispatch cases for the query ops (0x215/0x216/
0x218/0x21a), set ops (0x217/0x219/0x1ff/0x212/0x213) and lifecycle (0x1a2/0x1f7/
0x1fa). Query ops write results to operands like get-texture-size; set ops mutate
GfxState. Round-trip + distinct-slot tests pass; full suite 36 green (parity held).
