mtlcl410andClaude Opus 5.5 421a0dd9c9 fix(render): mesh triangles that share an edge leave no seam ...

The mesh sampler took each pixel's colour at its corner, and only when the
corner was strictly inside a triangle. A corner on an edge two triangles
share belonged to neither, so a Type 4-7 shading drew a white seam along
every shared edge that ran through the sample grid, and dropped pixels
along the mesh's own sides (a 30 x 30 square cut along its diagonal:
812 of 900 pixels; MuPDF 900).

Such a pixel now goes to the triangle that covers its centre, edges
included (Triangle::covers), and still takes the colour at its corner, so
every pixel that was drawn keeps its colour. Vendored hayro-interpret
patch 41.
