Adjust Title Bar Padding

[schorschii]

I'd like to suggest to unify the vertical and horizontal window title bar padding. The different distances from the close button to the top and right border, introduced with Mint 21, doesn't look correct to me even after months working with it.

Other desktop environments also do it like this and I think it looks more pleasant and accurate.

This change brings back the look from Mint 20.3, which was already perfect from my point of view.

I get a nice balance with 1px 5px, and 20px min.

SSD in dark, CSD on top.

In terms of screen real estate, this is the impact on the height of a 686px window:

• Padding 3px 7px --> 692px: 6px lost.
• Padding 1px 5px --> 688px: 2px lost.

2px 6px looks pretty good too.

Loss of 4px.

I like the idea with the larger padding too. I added a commit which implements your 2px 6px.

This is such a nice little improvement, thanks @schorschii.
