4 people 76fa06dbd5 Merged and stamped layers keep their content bounds in CMYK and Lab (#3886) ...

Merging or stamping converts the straight-RGBA composite into the
document's colour model. Transparent black converts to K = 100% in CMYK
and neutral a/b in Lab, so those pixels no longer equal the surface's
default pixel, prune() keeps them, and the layer's content bounds span
everything that was rendered: the whole canvas for Stamp Visible, Stamp
Down and Copy Merged, and for Merge Layers, Merge Visible and Merge Down
whenever an input may draw anywhere (a fill layer, even a masked one).

Fully transparent pixels are now written as the default pixel in both
conversion paths: photocraft_compose::flatten_to_surface (stamps, Copy
Merged) and engine pixels::composite_layers (merges). Only formats with
alpha are affected; over a Background everything stays opaque.

Tests: engine merge_transparent_bounds (Merge Layers, Merge Visible over
a transparent document, with a masked fill layer and onto a Background,
Stamp Visible, Stamp Down, undo) in RGB/Gray at 8/16/32 bit and CMYK/Lab
at 8/16 bit, and a compose unit test for flatten_to_surface. The masked
fill layer test fails on main (merged layer = full canvas in CMYK).
