[vim/vim] GTK4: Refactor hardware accelerated rendering backend (PR #20674)
Foxe Chen
Currently the glyphs are stored with each span of text (DrawNode). However when drawing text and it overlaps with an existing span of text, the existing span of text needs to be split. Knowing where to split in the glyph array is complicated and bug prone.
Refactor so that each cell contains an array of glyphs that represent that cell. Then when rendering the text, batch glyphs into a glyph string which is then used as a single text render node. The resulting code is much simpler, because now the DrawNode data structure only represents visual attributes, which means they can be easily split and clipped.
