- Specify 'vert' and 'vrt2' features when we render vertical text. - Set appropriate script so that harfbuzz-ng can use the features. This way, we will see the proper vertical text rendering when we specify 'text-rendering: optimizeLegibility'.

Hi Tony, Could you take a look? I think we should resolve vertical text rendering issue on complex text path before transition.
