## Description
Shears a shape around the y-axis the amount specified by the `angle` parameter. Angles should be specified in radians (values from `0` to `TWO_PI`) or converted to radians with the [](sketch_radians) function. Objects are always sheared around their relative position to the origin and positive numbers shear objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling `shear_y(PI/2)` and then `shear_y(PI/2)` is the same as `shear_y(PI)`. If `shear_y()` is called within the `draw()`, the transformation is reset when the loop begins again.
Technically, `shear_y()` multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the [](sketch_push_matrix) and [](sketch_pop_matrix) functions.
Underlying Processing method: [shearY](https://processing.org/reference/shearY_.html)
## Signatures
```python
shear_y(
angle: float, # angle of shear specified in radians
/,
) -> None
```
