I attached a patch for defect [ #10531: vf_drawtext causing font
rendering jitter after libharfbuz commit. ]
Before the patch the width of a text line was measured up to the
rightmost visible pixel of the last character.
Pros: the right padding specified with the boxborderw parameter is exact

Hi, I'm new to contributing to ffmpeg!
I modified the drawtext filter to improve text rendering and add some
features. You can find a high level description of the changes at this

Hello ffmpeg team,
I'm working on an enhanced version of the drawtext filter and would like
to discuss with you about a minor change in its behavior related to line
spacing management.
In the current implementation the space between two lines of text is set
