Fix size of clipped text glyphs. (#8197)

# Objective

Text glyphs that were clipped were not sized correctly because the
transform extracted from the `extract_text_uinodes` had a scaling on it
that wasn't accounted for.

fixes #8167

## Solution

Remove the scaling from the transform and multiply the size of the
glyphs by the inverse of the scale factor.
