/**

|
* @title Image recolor and rotation
|
|
* @brief Tint an image blue and rotate it using style properties.
|
|
*
|
|
* A style sets a grey background, a blue border, `image_recolor` to
|
|
* blue with `image_recolor_opa = 50%`, and `transform_rotation = 300`
|
|
* (30 degrees). The style is applied to an `lv_image` whose source is
|
|
* `img_cogwheel_argb`, then the image is centered on the active screen.
