3 people 3f8536868e image.analysis.recordMeasurements: refuse an area too large to measure instead of overflowing (#1184) ...

Fixes #933. With no selection the whole document is measured, and
`selection_mask` sized its mask with `r.width() * r.height()` in u32. A legal
65536×65536 document (2^32 pixels) overflowed the product, so `run` panicked
and dispatch reported an internal error; in release the product wraps to 0,
`gray_image` still renders the full region (~64 GiB of f32 RGBA) and
`measure_features` then indexes the empty mask.

`selection_rows` now computes the pixel count in u64 before anything is
allocated and refuses more than `MAX_MEASURE_PIXELS` (400 MP) with an error
that says to select a smaller region; the mask is sized from that checked
count. The measurement label counter is also bumped only after the rows are
computed, so a failed measurement no longer skips a number.
