Project 0.5:
- Separated image scaling from image display. Image scaling method calculates and stores coordinates of top left and bottom right corners of scaled image.
- Altered image bar loading algorithm to use left-most thumbnail as reference anchor rather than center image.
- Key press events properly trigger image bar scrolling if the newly selected image is not shown in the image bar.
- Mouse click event behavior implemented. Clicking on an thumbnail in the image bar selects that image and expands the image.
