Description Nikolas Zimmermann 2022-08-29 02:02:28 PDT

The screen scaling factor for font sizes (see RenderSVGInlineText::computeNewScaledFont) evaluates to 1.0 in LBSE.
Therefore the legacy engine / LBSE produce different visual text rendering results at present (glyphs are scaled, not the font itself).

Fix that to achieve pixel perfect rendering results between LBSE / legacy engine.
