dotCooCoo bbcb886a40 Perspective: a stored projection whose determinant overflows reads back at a w row of 1 ...

A stored projection whose determinant is not finite is read back as the
same map divided by the largest magnitude in its w row, the scale the
overflow branch of conjugated already uses, so points that overflowed at
the stored scale draw: the identity with every entry 1e308 maps (2, 2)
to (2, 2). The overflow branch of inverse scales the map so that the
largest of the products its determinant sums is near 1, so a map with
large entries and a small w row, such as a scale by 1e305 with a move
by -3.9e307, is still inverted and read back.

The two overflow tests in persp_text.rs build their stored projections
with a w row of 1, so they still overflow after the read-back.

Cargo.toml

Rename DrawCraft → VectorCraft: crates (vectorcraft-*), apps, binaries, types, env vars, docs, examples (.vectorcraft); old .drawcraft files and preferences still load. Fix: text bounds exact after opening a file; selection no longer marks a document modified (dirty = content differs from the saved document). Screenshots and renders regenerated.
