[Feature]: Add unit / pixel unit for panel size

[thefeymesaleng]

Describe the feature

It will be convenient to have other units (px etc) supported for sizes (minSize, maxSize etc). Currently it's not clear which unit is supported based on documentation, but I believe it's percentage based.

Other library example:
Take a look at q-splitter by Quasar Framework

Additional information

• I intend to submit a PR for this feature.
• I have already implemented and/or tested this feature.

Thanks for the suggestion ya @thefeymesaleng . However, we are not planning to support/implement this feature, as implementing pixel-based constraints added significant complexity (quoted by author himself) to the initialization and validation logic.

You can always use resizeObserver to compute the "percentage" yourself 😁
