Two examples in which your algorithm would fail:
E2 -->
+---------------+ Q : query point
^ | | E5 : nearest edge, no fill
| | + | E3 E1..E4 : edges with right fill
E1 | E5 | Q | |
| + | V
+---------------+
<-- E4
E2 -->
+---------------+ Q : query point
| |
| |
^ | <-E5 | E5 : nearest edge, left fill (hole)
| | +----+ | E3 E1..E4 : edges with right fill
E1 | | | Q | |
| +----+ | V
+---------------+
<-- E4
Note that both examples are valid topologies.
