Filled/outlined rectangles shown as snapping overlay are now enabled/disabled
independently with `snapping.overlay.[region|edge].bg.enabled` and
`snapping.overlay.[region|edge].border.enabled`.
To keep the default behavior, `*.bg.enabled` is yes and `*.border.enabled` is
no for hardware-based renderers, while `*.bg.enabled` is no and
`*.border.enabled` is yes for software-based (pixman) renderer.
Users can now use a filled rectangle as an overlay even with pixman renderer.
However, this may severely impact performance when used with translucent
`snapping.overlay.[region|edge].bg.color`.
This commit includes a refactor to use substruct `theme_snapping_overlay`
inside `theme` in order to pass it to `create_overlay_rect()` in a cleaner way.
Breaking changes is:
- `snapping.overlay.[region|edge].fill` is now removed.
Replace "preview" in rc.xml and themerc with "overlay" since "preview" sounds
like it shows the window content.
Breaking changes are:
- `snapping.preview.*` in themerc is now replaced with `snapping.overlay`.
- `<snapping><preview>` in rc.xml is now replaced with `<snapping><overlay>`.
Add ability to set width with percentage of monitor instead of just pixels.
With this the OSD sizes itself properly on both my 4k and 2k monitors.
example: 50% or 75% instead of 600, max 100%
...and change default values for the variables below to keep the
window-switcher look the same as it was at the last release.
osd.window-switcher.padding = 4
osd.window-switcher.item.padding.y = 1
osd.window-switcher.item.active.border.width = 2
...by reading <config-dir>/themerc-override where <config-dir> is normally
$HOME/.config/labwc can be other locations as described in labwc-config(5)
and can also be specified by the command line option -C.
The reason for supporting theme override is to give users more fine-
grained control of settings without making local copies and modifying
themes.
Add theme options:
- menu.separator.width
- menu.separator.padding.width
- menu.separator.padding.height
- menu.separator.color
Support separator lines defined by <separator />
Note that separator labels (with text) defined by <separator label="" />
are not supported.
