Subject: [PATCH] Drawing extents include solids placed through inserts

Zoom Extents skips an insert's marker wire and counts solids through
their meshes, but only model-space meshes were read: a drawing whose
solids all sit in blocks had no extents and the view did not move.
The instanced block meshes now count with their placed bounds.
