The length of each handle is not allowed to be more than the horizontal distance between (v1-v4). This is to prevent curve loops.
This function is very similar to BKE_curve_correct_bezpart(), but allows a steeper tangent for more snappy animations. This is not desired for other areas in which curves are used, though.

Ensure the FCurve is a proper function, such that every X-coordinate of the timeline has only one value of the FCurve. In other words, removes duplicate keyframes.
Contrary to BKE_fcurve_merge_duplicate_keys, which is intended for interactive use, and where selection matters, this is a simpler deduplication where the last duplicate "wins".
Assumes the keys are sorted (see sort_time_fcurve).
After deduplication, call BKE_fcurve_handles_recalc(fcu);

Get the first and last index to the bezt array that satisfies the given parameters.
| selected_keys_only | Only accept indices of bezt that are selected. Is a subset of frame_range. |
| frame_range | Only consider keyframes in that frame interval. Can be nullptr. |

High level function to get an f-curve from C without having the RNA.
If there is an action assigned to the id's AnimData, it will be searched for a matching F-curve first. Drivers are searched only if no valid action F-curve could be found.
r_driven) is optional and may be NULL.r_driven to True in case a valid driver F-curve is found, but will not return said F-curve. In other words:FCurve* and *r_driven = false.NULL and *r_driven = true.NULL and *r_driven = false. Definition at line 211 of file blenkernel/intern/fcurve.cc.

| void sort_time_fcurve | ( | FCurve * | fcu | ) |
This function sorts BezTriples so that they are arranged in chronological order, as tools working on F-Curves expect that the BezTriples are in order.

| void testhandles_fcurve | ( | FCurve * | fcu, |
| eBezTriple_Flag | sel_flag, | ||
| bool | use_handle ) |
Update handles, making sure the handle-types are valid (e.g. correctly deduced from an "Auto" type), and recalculating their position vectors. Use when something has changed handle positions.
| sel_flag | The flag (bezt.f1/2/3) value to use to determine selection. Usually SELECT, but may want to use a different one at times (if caller does not operate on selection). |
| use_handle | Check selection state of individual handles, otherwise always update both handles if the key is selected. |
