Text not vertically aligned in BMenuItem

Description

After working with getting CalendarView centered, more things pop out as not being centered properly.

This time it's every single BMenuItem.

With default settings of "Noto Sans Display"@12pt, the rendering works out to be just fine. However, at 16pt, or changing to a different font like Inter, there is a 1px misalignment. See attached file for comparison -- left is current rendering @16pt, right is fixed.

I've confirmed that right rendering is, well, right :) by recreating BMenuItem in CSS and checking it in Chromium.

The issue comes from the following line:

fSuper->MovePenBy(0, menuPrivate.Ascent());

This takes neither padding (3px) nor border (2px) into account. The correct solution is

float height = menuPrivate.FontHeight() - menuPrivate.Padding().top * 2;
fSuper->MovePenBy(0, 2 + menuPrivate.Ascent() + (height - menuPrivate.FontHeight())/2.0);

which simplifies to

fSuper->MovePenBy(0, 2 + menuPrivate.Ascent() - menuPrivate.Padding().top);

I've tested "Noto Sans Display" at 12/16pt and Inter at 12/16pt and all render properly (i.e. same as Chromium) with the above change.

Looking closer, the icon (Alt) is also slightly misaligned -- it should be 1px higher as well.

And the text next to it (1) needs the same treatment as well.

if you already know what the fix would be why not submit it to review directly? :)

Replying to nephele:

The icon and text next to it are still not aligned. Wanted to take a fresh look at this the next day.

I ran into the same issue with Tracker renaming files depending on font and font size the text box is sometimes off a pixel left or right compared to the file name string. The text should be in exactly the same location every time.
