This patch adds initial cursor support for the blade tool, with bitmaps
for 16x16, 24x24, and 32x32 cursors.
Additional Changes:
- Locked strips now show a "stop" icon when hovered over.
- Previously, the frame to split was truncated when clicking in between frames.
Now, round to the closest frame.
- Previously, the blade operator was able to select padded strip handles
outside of strip bounds. This bug has been resolved, so that selection with
the blade tool can only happen via box-select passthrough.
