//initially it was supposed to be one anime per one REFIT_SCREEN
// but this leads to large delays switching screens to initialize Film sequence again and again
// otherwise anime depends on theme and should be a member of XTheme
// then it should contain Screen->ID for each film
// but for next future we want to have other animated images in addition to screen->titleimage
// so let it be frames arrays each with own purpose (Id)
//
// XTheme contains Cinema which is an array of FILMs
// Each Screen contains a pointer to a FILM. And moreover titleFilm, or BackgroundFilm or even entryFilm
// Next problem is a timeout between frames.
// A theme contains images with indexes 1,2,5,6 for one Id.
// This Id contains fixed timeout between frames. Then next updateAnime Index will be compared with current tick
// if yes then update. Static index?
//
// in the far future I'll plan to make dynamic SVG: parse SVGIcon with a variable argument
// and then rasterize it. Real SVG contains constants only so it will be new dynamicSVG.
// then Entry->Image should be reparsed each time it created or contains flag to update every frameTime
