Fix text spacing with vertical fonts. #7687 and #11526.

Browse source 
When the writing mode is vertical, we have to reverse
the sign of spacing since we are subtracting it from
current.y. We have to add it to current.y.
See 9.4.4 Text Space Details, https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G8.1694762
