Added setting to toggle drawing of title bar separator
Summary:
Adds a new settings on Breeze theme which allows the user to turn off the title bar separator drawn
Rationale behind this patch:
From what I understand, the separator is seen as a design choice so I won't argue over it, not to mention something like this is entirely subjective.
However, I personally dislike the separator, especially on darker windows. The only way to get rid of it is to either make a custom color scheme for each application so the colors match exactly or run a patched version of breeze (which is what I do). Before using my Breeze patched version I searched on the net on how to remove it, which led me to several threads with other users wanting to toggle it off which is why I make this patch public.
Below are screenshots where the separator is especially noticeable and in my non-design-expert opinion kind of distracting. I think it's a positive addition. Looking forward to your opinions on the matter.
Test Plan:
- Use default breeze theme
- Check the enable/disable the new setting
