GameLib map/area/terrain units, PRTerrainLib Terrain/TextureSet,
PythonBackground(+Module) and ColorTransitionHelper ported verbatim;
pending stand-ins and background module stubs removed. Hand edits:
BeginEnvironment's pointer tag via uintptr_t, LoadWaterMap reads the
file's 32-bit longs. Terrain draw passes stay platform no-ops (Godot
draws the terrain). RecordingDevice gains textures, buffers and render
targets; orthographic draws become UI commands so CPythonMiniMap's
masked tiles show through minimap_image_filter in python_ui_surface.

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.
