The current `test/geo_alignedbox` tests fail on 32-bit arm due to small floating-point errors. In particular, the following is not guaranteed to hold: ``` IsometryTransform identity = IsometryTransform::Identity(); BoxType transformedC; transformedC.extend(c.transformed(identity)); VERIFY(transformedC.contains(c)); ``` since `c.transformed(identity)` is ever-so-slightly different from `c`. Instead, we replace this test with one that checks an identity transform is within floating-point precision of `c`. Also updated the condition on `AlignedBox::transform(...)` to only accept `Affine`, `AffineCompact`, and `Isometry` modes explicitly. Otherwise, invalid combinations of modes would also incorrectly pass the assertion.
