Add window rules for mouse and touchpad scroll factors

[myQwil]

Describe your PR, what does it fix/add?

There are scenarios where I want the scroll factor to be different on a per-window/application basis. This change adds window rules for overriding the global scroll factors. There is one for the mouse scroll factor (scrollmouse) and one for the touchpad (scrolltouchpad)

Example:

hyprland.conf:

# Faster scrolling in Dolphin
windowrulev2 = scrollmouse 3, class:org.kde.dolphin

# Even faster scrolling in Sublime Text
windowrulev2 = scrollmouse 5, class:sublime_text

Is there anything you want to mention? (unchecked code, possible bugs, found problems, breaking compatibility, etc.)

Not that I can think of.

Is it ready for merging, or does it need work?

Ready for merging.

Just tested on my touchpad, lgtm.

Something's still off. The touchpad scroll factor is using input:touchpad:scroll_factor but then doesn't get overridden by scrolltouchpad window rules. It does, however, get overridden by scrollmouse window rules.

EDIT: It's been fixed. scrolltouchpad was sending the window's scrollMouse property instead of scrollTouchpad.

can you rebase on main pls?

Okay, made the following changes:

• ConfigManager.hpp: made the PHLWINDOW parameters refs
• InputManager.cpp: removed redundant parentheses
• KeybindManager.cpp: switched to using std::stof
  • was going to add a try catch, but it's already in one for catching prop value parsing errors.

Moved the factor override past all the potential early return cases.
