Also, add a `convert-bounds-padding` parameter that defaults to adding 3 units (= pixels, usually) on each side of a pict when converting to a format that supports padding. Combined with changes to Scribble to use the new formatting, the extra padding solves the long-standing problem of rendering picts and having an edge (especially the bottom and right) cut off due to rounding effects. For example, see `file-icon` in section 7.1 of the `pict` documentation. The choice of 3 pixels is more or less arbitrary; it covers the case of edge pixels and italic fonts for typical font sizes, but it obviously won't cover all drawing outside of a bounding box, as for the documentation example `(desktop-machine 1 '(devil plt))`. |
