Wacom tablet support in the Windows/Java TurboVNC Viewer + support newer Wacom tablets on Windows

[dcommander]

This is the biggest feature that exists only in the Windows native viewer, and it exists only in that viewer because I tried and failed to implement it in the Windows/Java TurboVNC Viewer. However, after having implemented Wacom support in the Mac/Java TurboVNC Viewer, I have some new ideas regarding how to make it work in the Windows/Java TurboVNC Viewer. Fortunately, I still have the code from the failed experiment.

Furthermore, it seems as if we will need to use the Windows Ink API, rather than Wintab, in order to support newer Wacom tablets. It may also be necessary to use the Wintab API for older tablets, perhaps as a fallback mechanism. This would all happen within the Windows TurboVNC Helper.

Removing this feature from the Windows TurboVNC Viewer Migration milestone. That milestone is meant to reflect potential feature regressions from dropping the Windows native TurboVNC Viewer in favor of the Windows/Java TurboVNC Viewer. Since newer Wacom tablets aren't supported in the current Windows TurboVNC Viewer anyhow, and since Wintab has a lot of other problems, the current lack of tablet support in the Windows/Java TurboVNC Viewer isn't a major feature regression.
