modules/flow: restore previous Z depth
While optimizing the threaded rendering in commit 6d6c141, the pos.{xy} expanding from 0-1 to -1..+1 were eliminated from the inner loops in favor of just having the positions always in -1..+1 coordinates. But I missed that it was only the x/y coordinates which were being expanded, with .z being left in the 0-1 space, which had a desirable aesthetic effect of condensing the Z space, flattening everything. This commit undoes that, without reintroducing the expansion to the inner loops. It's a bit crufty because now .z is treated exceptionally throughout as 0..1 while {.x,.y} are in -1..+1, but it's fine for now.
