I'm experimenting with adding semantic highlighting in cquery using the decorator API (vscode.window.createTextEditorDecorationType and vscode.window.activeTextEditor.setDecorations) after the decoration performance improvements coming in 1.18.

It'd be extremely useful if I could use the decorators to control more aspects of font rendering, such as weight (bold, italic, etc) and size. Right now I can control underline, but I think it is very visually busy.

If a PR would be accepted for this I can investigate contributing one.
