Tasks/Questions

1. [2] Update PicViewer2 so all the fields use a PicWatcher with clamp functions as specified in Tutorial 8. Include the full code of MainActivity.kt as your answer to this question.
2. [2] Remove the title bar from the screens. Make sure your solution works for both light and dark modes.
3. [4] Add a title screen with a continue button. The title should be "Picture Viewer Demo". When the title screen's continue button is pressed the main activity should be shown.
4. [4] Add the name of the picture as a title above the image, centered. It should be in a Body3 bold font. You'll need to assign each picture a name.
5. [2] When you click on the image title, have it open up a DuckDuckGo image search for that title in the system web browser. We can do this with a specially crafted URL. For example, if the image title is kittens, we can initiate the search by visiting the page https://duckduckgo.com/?q=kittens&iax=images&ia=images
6. [4] Add a touch event handler that allows the picture to be dragged to different positions on the screen. As the image is moved the X and Y fields should be updated.
7. [2] When the device is rotated, is the position of the image preserved after it is dragged? Why or why not?
