Hi Glenn, I have now started looking into the alignment issue and tracked it down to the way that the bounding box is expanded the glyph size plus the margin required for the SDF/mipmapping sampling. The margin for the SDF is bigger than is require for the greyscale so the bounding box ends up being bigger.
This is good for rendering and culling purposes as it makes sure that the whole glyph is always rendered, but it is adversely affecting the alignment set up, and usage cases like yours. It looks like I need to decouple the margin from contributing so much to the alignment calculation. Not sure yet what the best thing to do is.
