[FR] Add NumericUpDown

Hello,

I would like to request a feature for a NumericUpDown control. This is a common widget that allows users to enter and adjust numeric values using a textbox and arrows or the mouse wheel. It is available in other frameworks such as Qt (see https://doc.qt.io/qt-6/qdoublespinbox.html and https://doc.qt.io/qt-6/qspinbox.html).

I think this would be a useful addition to the graphics framework, as it would provide a more user-friendly and intuitive way to input numeric data. Currently, the only option is to use a textbox with a validator, which is not very convenient or elegant.

Thank you for your consideration and your hard work on this project.
