ScreenshotUI

This is a UI that will appear after a user takes a screenshot to give them various options.

Intended Functionality

• Screenshot keycombo launches the service through a broadcast intent
• Server takes a screenshot, passes it to the UI when it's created
• ScreenshotUI shows the screenshot, along with options
• Crop button will discard the screenshot and initiate a partial screenshot (does not return to UI)
• Scroll button will discard the screenshot and initiate a scrolling screenshot (does not return to UI)
• Edit button will save the screenshot and send a photo edit intent
• Cancel button will discard the screenshot and close the UI
• Share button will save the screenshot and send a file share intent
• Save button will save the screenshot and close the UI

TODO

• Decide if back button should function as cancel or save (probably save)
• Impliment broadcast receiver
• Add button functionality (requires some system APIs, so it will be done last)
• UI close animation?
• Add hardware accelleration flag to window params
