What does the pull request do?

Updates AccessText.RenderCore logic to align the rendered underline to pixel bounds for clarity.

What is the current behavior?

The DrawLine method was rendering at non-pixel bounds, which made lines very blurry.

This simple XAML shows blurry underlines:

<AccessText Text="_Access text" />

What is the updated/expected behavior with this PR?

Now lines render crisply like this:

How was the solution implemented (if it's not obvious)?

Rounded line coordinates to render on pixel bounds.
