Inverse perspective

```
Hello

Unfortunate misunderstanding. Models are visualized with an inverted
perspective: far edges larger than nigh. This is well illustrated in the
examples of "sandiego", "map3d", "iphoneg4".
Using the latest version.
Can you please tell how to fix it.

Thank you.

Start with the sandiego, map3d, and iphoneg4 examples and compare their model visualization, focusing on the reported inverted perspective. Determine the relevant source entry point, then verify that far and near edges render with the intended relative sizes in all three examples; no file or test is named, so repository exploration is required.
