Renderer: Revert to using local WallEdges in writeAllWallSections
On second thoughts, the existing map renderer is simply not ready to support such a fundamental design change. Until the renderer is able to draw the world as homogeneous chunks of geometry, internalization of WallEdge in SectorCluster is pretty much impossible.
Todo:
Revise the map geometry pipeline to work using wall geometries that have already received "edge divisions" at a much higher level.
Also, deferring the drawable geometry copy into the render list's internal vertex buffer until it has been fully prepared not only adds significant and unnecessary overhead but also complicates the whole pipeline. This is due to the need to drag map data and/or structures deep into the inter bowels of the renderer. (WallEdge being one such example of data that does not belong in the guts of the renderer).
Instead, an API should be introduced to reserve storage in the vertex buffer as soon as possible so that map geometries can be constructed in-place (for now) in a form that is immediately drawable when done.
