package: slim
version: 1.4.0-0devuan2

slimlock shows two text-labels (welcome_ and password_). Placement is
relative background, but should be relativepanel-image, like slim.
This is invisible when using a current Devuan theme(s): The panel-image
is placed at 0,0, which equalises the origins in slim and slimlock.
Fix: small patch included, mostly comments in the source as patch-notes.
Maintainers may use it as they see fit.
Patch file:
"slim__slimlock_label_positions__welcome_and_password__bugfix.patch"

System: daedalus
Kernel: 6.3.6-1-liquorix-amd64
((chimaera's 1.3.6: Patch applies with comments rejected. Seems to work
for welcome_ and username_ (not hidden), but not for password_)).

Part II:
Dear maintainer,
beside the bug fix, there is a small piece of code to handle in-line
comments in config files, which is attached too.

Proposed feature: Handle in-line comments in config files (slim.theme).
Reason: Before realising the error, I used in-line comments during
theme'ing.
Patch file: "slim__in-line_comments_in_config_files__addon.patch"
This may or may not be considered useful.

Both are tested, but I'm not really a software developer.
Feel free to contact me for any issues.

Thanks for devuan, slim and all the effort!
Regards,
Thomas
