Improve quality of YUVY and UYVY rendering
Idea is to upload YUYV/UYVY data as 2 textures and use GL_LINEAR like
in biplanar formats. Having proper interpolation of only one texture
(using e.g. mix function) resulted in vertical and horizontal 1 pixel
stripes depending on scale. The reason was float precision and
unexpected value of fract function. Additionally branching in shader
is expensive so this solution should be more performant.
