    // Predstavljajte si, da imamo 2100:900 video v 1600:900 škatli, zoomStep = 0.1. Če bi širino računali po formuli:
    // 
    //     širina = širina_videa + (širina zaslona * zoomStep)
    //     
    // Potem bi bila nova velikost videa 2260 x 990. Razmerje stranic: 2.28 (moglo bi biti 2.33 — video je popačen).
    // Zaradi tega novo širino rajši povečamo za razliko_v_višini * razmerje_stranic
    // 
    //     2100 + (900 * 0.1 * (2100/900)) =
    //                 2100 + (90 * 2.333) = 2310
    //
    // Razmerje stranic (2310x990) je tako 2.333 — tako, kot bi moglo biti.
    // 
    // 
    // ============================================================================================================
    // 
    // Why did we calculate width this way?
    // 
    // Imagine we have a 2100x900 video in a 1600:900 container, zoomStep = 0.1. If we calculated width using this:
    //
    //     width = video_width + (container_width * zoomStep)
    //     
    // then the new size would be 2260 x 990. This gives us an aspect ratio of 2.28 instead of 2.33 (which is what it
    // should be). Because of that we rather increase the width by delta_height * aspect_ratio:
    //
    //     2100 + (900 * 0.1 * (2100/900)) =
    //                 2100 + (90 * 2.333) = 2310 
    //
    // This gives us the correct aspect ratio and prevents video deformations.
