This adds a new `tray-foreground` config option, and uses it instead of
the `tray-background` setting to build up the `_NET_SYSTEM_TRAY_COLORS`
property. I'm pretty sure that the previous behavior was a mistake (this
was introduced in 94298741b6 which is a
pretty large diff). For me and some other people, this results in a
black icon being drawn on top of a black background, which is pretty
useless! I would say that this diff fixes
https://github.com/polybar/polybar/issues/2235. Note: the old code dealt
with `unsigned int` and maxed values out at 0xff. The new code deals
with `uint16_t` and maxes values out at 0xffff. I haven't found the
relevant documentation to justify this change, but from manually
testing, I'm pretty confident this is the right change.
This all matches pretty closely with this code from i3:
[`i3bar/src/xcb.c::init_tray_colors`
code](43e805a00d/i3bar/src/xcb.c (L1490-L1522)),
which you can see also uses the bar's foreground color and maxes values
out at 0xffff, not 0xff.
If you merge this up, I think we should also update
https://github.com/polybar/polybar/wiki/Configuration#bar-settings to
mention the new settings.
Fixes#2235
* build: Add -Wsuggest-override
We should always use the override specifier when overriding virtual
functions. This helps prevent errors when a subclass tries to create a
function with the same name as a virtual function in a super-class but
with a different purpose.
* clang-format
* Upload logs on failure
* Add override to unsupported.hpp
* cmake: Make -Wsuggest-override flag conditional
This patch adds support for observing multiple slices of the desktop background.
This is used for the tray so that it doesn't have to rely on the bar's rect to
get the desktop background. In particular, it now handles the case where the
tray is not contained fully within the bar's outer rect (for example, when using tray-offset-{x,y})

We need to use positions relative to the position of the bar for indexing into
the background image slice, but the code used absolute ones.
This worked fine as long as absolute positions are the same as relative
positions (this is the case for a bar located at (0,0), so if bottom = false).
But for bottom bars (where the bar position is not (0,0)) this was wrong which
caused the tray background to be black (out of bounds for the background slice).
