// When you upscale sprite will sample invalid data of the texture. The idea is to add a subtexel offset

// 0.5: initial offset of texture (not sure it is always true)
// L: length of primitive in pixels (after upscaling)
//
// Full formulae is
// 0.5 + (L - 1)* (WH-offset)/L < WH
//
// A reduced formulae is: (hypothesis 1:1 mapping => L == s*WH)
// offset > ((0.5)*s -1)/(s-1/WH)*16
