An odd value of fe.height lead to the indicator disappearing. This was
due to the buffer size no longer being a multiple of the buffer scale.
This commit fixes the issue by checking both height and width to be a
multiple of scale.
This is done early to avoid excessive re-calls of create_buffer if the
buffer_height != new_height in render.c line 314 (now 318).
This commit adds a new command line option called --font-size to
specify a fixed font size in the indicator. The default value for
font-size is 0, which means that the text will autoscale. Any other
positive value will result in a fixed text size.
Displays the current keyboard layout below the unlock indicator if more
than one xkb layout is configured or the show-keyboard-layout option is
given. The text is displayed with a background box.
Adds commandline options for text color, background color and border
color of the box as well.
Keeps track of unsuccessful authentication attempts via an int counter
in the state struct. Displays on the unlock indicator, but will be
replaced by the Caps Lock text if enabled.
The -c/--color option no longer sets BACKGROUND_MODE_SOLID_COLOR (which
disables the background image) and the background color is now set in
all cases. One can still use --scaling solid_color to disable display of
a background image.
As a consequence, there is now only one possible default background
colour (white), regardless of whether a background image is given or not.
This implements customization for the indicator as proposed in sway#2788 with comments from sway#3367 in mind.
The default behaviour does not change exept for the caps lock text color.
Since these changes seem to be lost in the split I've remade them.
