- Only use the fixed table layout algorithm if the table has a width. - Calculate column widths using only the first row's cells. see https://www.w3.org/TR/CSS2/tables.html#fixed-table-layout fixes #2355 fixes #1432
The quality of the results from imagescale vary depending on the image type and scaling mode. imagecopyresampled appears to produce more consistent results. fixes #3496
Before this change Dompdf would only resolve content for in-flow children of auto-width (content-defined width) parents. Because content resolution also resolves counters this was resulting in incorrect counter resolution for out-of-flow elements (e.g. position: absolute) inside auto-width parents. fixes #3611
