---- Component to handle scroll content.
--- <b># Overview #</b>
---
--- The Scroll component is designed to handle scrollable content and consists of two nodes: the scroll parent and the scroll input.
---
--- The scroll input represents the user input zone and remains static.
---
--- The scroll parent is the movable part of the scroll and changes its position.
---
--- The initial scroll size can be set by adjusting the size of the scroll parent.
--- If the size of the scroll parent is smaller than the scroll input size, scrolling is not available.
---
--- <b># Notes #</b>
---
--- • By default, the scroll style includes inertia and extra size for a stretching effect.
--- These settings can be adjusted using the scroll style settings.
--- For more details, refer to the scroll style settings.
---
--- • "Points of interest" can be set up for the scroll.
--- The scroll will always be centered on the closest point of interest.
--- This feature allows creating a slider without inertia and with points of interest on each scroll element.
---
--- • The scroll content size can be adjusted using the scroll:set_size(node_size) method.
--- This method sets a new size for the _content node.
---
--- • Inertial scrolling mode can be enabled or disabled using the scroll:set_inert(state) method.
---
--- • The extra stretch size can be adjusted using the scroll:set_extra_stretch_size method.
---
--- • Multitouch is required for scrolling. The scroll component correctly handles
--- touch ID swaps while dragging the scroll.
