描述

Ctrl is the shortcut for the Line tool to lock the current angle. But currently, it takes effect if Ctrl is held before the click and drag for drawing a new line, which is not desired, because Ctrl is also used to allow drawing a new line snapped to the endpoint of an existing line (rather than dragging around that endpoint). Ctrl should only lock the line's angle if it is pressed after the dragging is already occurring, whether that's for a new line or for dragging the endpoint of an existing line.

研究方向
Investigate the line tool's input handling in the Graphite codebase. Look for where Ctrl keydown events are processed for the line tool. Consider modifying the logic to only apply angle locking after a drag has started. Check the comments on the issue for any specific guidance.
