I have just committed some editorial changes for section 3.3, but while reviewing it i also ran into the following issues, which i think need to be addressed:

what kind is meant here?

[2]

This ignores scripts without a hanging baseline. I suggest the following:

The explanatory text in the images (which is crucial to understanding the text) is very hard to read, because of its size. Please redesign the images.

[5]

or X1 to descent of the last line or line XN

The meaning of this is hard to decipher.
