Make titlebar metrics configurable

[probonopd]

A common complaint about the upstream Breeze theme is that the title bars are too big and cannot be configured in a fine-grained way. I understand that BreezeEnhanced was made to make it more configurable, and I think it would be nice if titlebar metrics could also be made configurable via breezerc.

For example, I would like to achieve this result:

Especially, I would like to be able to set:

• The title bar radius in pixels
• The height of the title bar in pixels (e.g., 22 pixels, independent of font size)
• Padding in the title bar in pixels (not in "units of small spacing", whatever that is supposed to be)

See breezedecoration.cpp and breeze.h in

https://github.com/helloSystem/BreezeEnhanced/commit/27a05ac4fb3b0e397acb468ae929b7167fe18791

for the type of changes I would like to see made configurable, so that one doesn't have to fork BreezeEnhanced just to make these kinds of configuration changes.

Your feature request is quite valid.

But, as I said in https://github.com/tsujan/BreezeEnhanced/issues/31#issuecomment-822788786, I don't consider BreezeEnhanced as my program. It's rather the result of applying some patches of mine to Breeze, for using it with Kvantum. To me, it's 99% Breeze. What I do here is only updating it whenever needed. Having a limited amount of free time, which I spend on my own projects, I couldn't do that if it gets too different from Breeze.

So, I think the only way is forking. Sorry!

Had you ever tried to get your improvements into upstream Breeze?

Years ago, I applied a simple patch to Breeze to make its ugly gradient smooth. I proposed that patch (I don't remember where) but they didn't accept it. Then I applied a few more patches to make it more beautiful and to change its title-bar font outside KDE. So, I'm sure they won't accept any of those patches.

Would you happen to know how to disable the right-click menu that appears when one right-clicks on the window title? It contains a KDE Plasma specific menu entry that does not even work when the full KDE Plasma desktop is not installed.

Strange! Here, the title-bar doesn't have a right-click menu. I don't remember if there was a KDE option that I activated or they removed the menu — or even if that menu was there in the first place.

I need to disable this entirely, since no KDE Plasma is installed on my system and some of the options in the menu need it.

Here, the same menu appears on left clicking the window icon, not right clicking the title-bar:

I don't know where its source is. I think it's quite useful.
