<h1>Module <code>Scroll</code></h1>
<p>Component to handle scroll content.</p>
<p>
<b># Overview #</b>
<p> The Scroll component is designed to handle scrollable content and consists of two nodes: the scroll parent and the scroll input.
<p> The scroll input represents the user input zone and remains static.
<p> The scroll parent is the movable part of the scroll and changes its position.
<p> 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.
<p> <b># Notes #</b>
<p> • 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.
<p> • "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.
<p> • 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.
<p> • Inertial scrolling mode can be enabled or disabled using the scroll:set_inert(state) method.
<p> • The extra stretch size can be adjusted using the scroll:set_extra_stretch_size method.
<p> • Multitouch is required for scrolling. The scroll component correctly handles
touch ID swaps while dragging the scroll.
