Text alignment

[WindowsNT]

This is the output of {[ c2/12 ]}, the "3" in the tuple is misaligned.

When debugging I saw that the top left rect (x,y) passed to DrawString may be the "bottom" of the text.

I need some help understanding the SetFontAlign parameters. For example, is the kAlignCenter both horizontal and vertical alignment?

Text alignment for tuplets for VGDevice::kAlignCenter | VGDevice::kAlignBottom.
I suggest to test various text alignments with your implementation, using text elements only. You can compare your output with the online guidoeditor.
e.g.

{
[
	\text<"right", textformat="rt">(a) 
	\text<"center", textformat="ct">(a)
	\text<"left", textformat="lt">(a)
]
}
