2V3-b: click on the ground to walk; read the terrain attribute map

Browse Source 
CScreen::SetCursorPosition and CPythonGraphic::SetCursorPosition are the 40250
bodies, so RenderGame builds the pick ray under the cursor each frame.
CPythonBackground::GetPickingPoint* march that ray as
CMapOutdoor::__PickTerrainHeight does, against the native CMapManager height
(PR_FLOAT_TO_INT's x87 rounding becomes floor); object picking waits for
CMapOutdoor. CMapManager::isAttrOn reads the packed <map>/<xxxyyy>/attr.atr
as CMapOutdoor::isAttrOn + CTerrain::isAttrOn do, and CheckAdvancing with its
collision checkers is verbatim (no map objects are registered yet). All of
this stays in the pending/platform layer and is marked ADAPTED.

port.login_flow clicks the ground below the actor after the key walk. The
actor walks to the picked point (334 cm offline), and the fake server sees
FUNC_MOVE, then FUNC_WAIT. It also checks that the actor's cell is free and
that its terrain block has blocked cells. port.login_live against the real
server passed (key 133 cm, click 296 cm), and python_game_render_test.sh
passes offline. MT_TEST_MODE=python_ui now adds the 3D surface, so the port
route can be played by hand.
