Fix galley width calculation being off due to subpixel binning (#7972)

- fix for https://github.com/rerun-io/reality/pull/1075 The galleys row size was calculated by looking at the last glyphs pos_x, which got changed to be rounded to integers when we added subpixel binning. This introduced a subtle bug which caused the width of galleys to be slightly off. This PR fixes this by looking at the actual cursor position instead, which is not rounded. Also added a test to ensure this is correct. Previously, for the second and last line, the `x` was too close to the `0`. <img width="48" height="67" alt="image" src="https://github.com/user-attachments/assets/a69a4cc3-b3f3-4553-ab92-73cb2e7a358c" /> --------- Co-authored-by: lucasmerlin <8009393+lucasmerlin@users.noreply.github.com>
