keyspersecond: init at 8.9

Description of changes

Closes #281453

This PR adds 1 package: keyspersecond
This is a java app, using Gradle as the build system.
Luckily, there were less gradle shenanigans than with other packages.

I used stripJavaArchivesHook to fix the timestamps in the jar file

I do not know if darwin also needs extra runtime libraries, sadly I cannot test it.

Tested basic functionality: it listens for keypresses when osu-lazer is in focus and updates the key counter accordingly on X11. Thanks for packaging it @TomaSajt!

Thank you for your work! Some suggestions:

• KeysPerSecond v8.9 has been released.
• Add the flag -Dsun.java2d.opengl=true in the command wrapper; otherwise, the background color cannot be translucent.
• Could you please also add a desktop entry?

I did a big restructuring of the whole derivation, hopefully this way its in a more "override"-able state.

I also dropped the usage of canonicalize-jars-jook in place of a better built-in solution (added by a patch file)

[TomaSajt]

I can't seem to be able to use the colors set in the color selector (bug?), so I don't know if the transparency fix works or not.

In the color config interface, there is a checkbox saying "enable custom colors". You need check that on.

Upon second thought, I think enabling this flag in the command wrapper may cause some problems when OpenGL is not supported? I do not have an environment to test that, though.

I'm using a dark theme, so most of the UI is pretty unintelligible, because of this that toggle button wasn't even visible to me.

I tried it out, and it wasn't working properly yet. However after debugging with J2D_TRACE_LEVEL=4 I figured out that libGL just wasn't able to be found, so I added it to libPath. It now seems to work OK

I used canonicalize-jars-hook to fix the timestamps in the jar file.
I used a built-in build flag inside gradle to have a deterministic timestamp in the jar file.

Cool! Do you think this can be generalized and used across nixpkgs?

I think we can, but mostly with manual patches.
See this comment for every solution I could find to not have to use canonicalize-jars-hook.

#272380 got merged, so you should adjust the code accordingly (it should be greatly simplified). See https://github.com/NixOS/nixpkgs/blob/master/doc/languages-frameworks/gradle.section.md

That's really great to hear, I've been excited to finally try it out.
