dotCooCoo d098d33188 Perspective: a stored projection whose determinant overflows is judged on a scaled copy ...

Homography::from_array accepted nine finite numbers only when det().abs()
was above 1e-15. With large entries the determinant can be inf - inf, so a
valid stored projection was rejected on reading and its type drew flat, or
it can overflow to inf, so a projection that cannot be inverted was
accepted.

When the determinant is not finite, inverse() now inverts a copy divided
by a power of two (largest entry between 0.5 and 1), and treats that copy
as not invertible when its determinant is at most 1e-15 times the largest
of the six products it sums. from_array and the overflow path of
conjugated accept such a map only when that inverse exists. Maps with a
finite determinant are judged as before.

Follows #4912.

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.
