#1 Support more touchpad vendor/model

[Alvin Wong]

Please support more touchpad vendor or model.

Supporting more touchpad will require the touchpad driver to provide certain APIs for the program to get the absolute finger position on the touchpad. Without the APIs, it may require a self-written driver (could be based on Linux drivers) to do so.

Here is an incomplete list of touchpad vendor and its status:

Vendor	Status
Synaptics	✓ Supported
ELAN	✗ Not supported
Sentelic	✗ Not supported

Please make a comment if you have other vendors to add.
