This commit adds `<windowSwitcher thumbnailLabelFormat="%T">` to configure the label text in each item in the thumbnail-style window switcher. Its format follows `<fields><field content="custom" format="">`.
This allows us to share common codes for dealing with osd items.
For example:
- Get the clicked osd item to focus its associated window
- Scroll the items when their total height is taller than output height
- add LAB_WINDOW_TYPE_INVALID in place of literal -1
- document more clearly that enum lab_view_criteria is a bitset
- other one-off replacements of integer values/types for consistency
Note: variables of type enum lab_view_criteria are already used
extensively throughout the code to contain combinations of the declared
enum values. I am not introducing any new usage here, just changing the
single uint32_t to be consistent with all the other usages.
Add custom field with subset of printf style formatting
to replace the original field formats.
Example:
<windowSwitcher preview="no" outlines="no" allWorkspaces="yes">
<fields>
<field content="custom" format="foobar %b %3s %-10o %-20W %-10i%t" width="100%" />
</fields>
</windowSwitcher>
Mono space font recommended. May need OSD width adjusted
