* @class LvglComponent
* @brief Component for rendering LVGL.
*
* This component renders LVGL widgets on a display. Some initialisation must be done in the constructor
* since LVGL needs to be initialised before any widgets can be created.
*
* @param displays a list of displays to render onto. All displays must have the same
* resolution.
* @param buffer_frac the fraction of the display resolution to use for the LVGL
* draw buffer. A higher value will make animations smoother but
* also increase memory usage.
* @param full_refresh if true, the display will be fully refreshed on every frame.
* If false, only changed areas will be updated.
* @param draw_rounding the rounding to use when drawing. A value of 1 will draw
* without any rounding, a value of 2 will round to the nearest
* multiple of 2, and so on.
* @param resume_on_input if true, this component will resume rendering when the user
* presses a key or clicks on the screen.
