### Description
implements wlr-tablet-v2 for drawing tablets and supports cursor emulation
Implements wlr-tablet-v2 for drawing tablets with cursor emulation.
Inspired by @guyuming76's [branch](https://codeberg.org/guyuming76/dwl/commits/branch/graphic_tablet), with coding help from @Palanix and testing by @Thanatos.
inspired by @guyuming76's [branch](https://codeberg.org/guyuming76/dwl/commits/branch/graphic_tablet), with coding help from @Palanix and testing by @Thanatos
- **Tablet area**: define the active drawing zone using the `tablet_pad` array
`{x, y, width, height}`, values range from 0.0 to 1.0 (as a fraction of the
tablet's full surface). Only input within this area is mapped to the screen.
- **Button bindings**: bind tablet pad and stylus buttons to compositor actions.
