This patch immediately realizes the scale and rotation components of
transformations at the point of transform nodes. The translate component is
still delayed and only realized when really needed to avoid clipping.
Transformed results are always realized in an expanded domain that avoids
clipping due to rotation or scaling. The size of the transformed domain is
clipped to the GPU texture size limit for now until we have support for huge
textures, that limit is typically 16k.
A potential optimization is to join all consecutive transform and realize
operations into a single realize operation.
Fixes#112332.
