Previously, `height` was derived from a manually chosen glyph (typically "I", Standard Cap Height) using FontBuilder, and `lineSpacing` was used inconsistently for layout logic as a height. Now, with the FreeType-based system: - `height` uses `face->size->metrics.height`, which includes the recommended line height with internal leading/line gap as defined by the font designer. - `lineSpacing` was removed - `GetCapHeight` uses the standard cap height + ascender to have a visual virtual alignment This change standardizes font metric usage: - Use `height` for vertical layout and line progression. - Use `GetCapheight` in layout engines like `CGUIText` or `CGUIString`, This ensures better alignment across fonts and consistent spacing in multiline text rendering. Fixes: #7962
