Before this change, "background-clip: text" was implemented by saving a Vector<Gfx::Path> of all glyphs needed to paint a mask for the background. The issue with this approach was that once glyphs were extracted into vector paths, the glyph rasterization cache could no longer be utilized. With this change, all text required for mask painting is saved in a nested display list and rasterized as a regular text.
