mtlcl410andClaude Opus 5.5 1cf6ca5579 fix(render): a stencil mask is drawn at the fill opacity once (#2975) ...

hayro-interpret draws every image XObject inside a transparency group
that applies the fill opacity (ca). A stencil mask (/ImageMask true)
also takes the fill colour, with that same alpha, as its paint, so the
opacity was applied twice: at ca 0.5 a mask was drawn at 25 %, at
ca 0.25 at about 6 %. Rectangles and raster images were right.

Vendored hayro-interpret patch (36) resets the fill alpha to 1 once
the image's group is pushed, before the stencil's paint is taken; the
saved state is restored after the image. Type 3 glyph and pattern
stencils take their paint from the glyph or pattern and are unchanged.
