Functions
Internal Gesture Utilities
Border gesture has two types: WM_GESTURE_CROSS_RECT: starts a cross, on mouse click it changes to border. WM_GESTURE_RECT: starts immediate as a border, on mouse click or release it ends. It stores 4 values (xmin, xmax, ymin, ymax) and event it ended with (event_type).

Straight Line Gesture
Gesture defined by the start and end points of a line that is created between the position of the initial event and the position of the current event. Straight Line Gesture has two modal callbacks depending on the tool that is being implemented: a regular modal callback intended to update the data during the execution of the gesture and a one-shot callback that only updates the data once when the gesture finishes. It stores 4 values: xstart, ystart, xend, yend.

WM_gesture_straightline_oneshot_modal()

This modal one-shot callback only calls exec once after the gesture finishes without any updates during the gesture execution. Should be used for operations that are intended to be applied once without real time preview (like a trimming tool that only applies the bisect operation once after finishing the gesture as the bisect operation is too heavy to be computed in real time for a preview).
