Use:
ratio(vec2 st, vec2 st_size)
#ifndef FNC_UNRATIO
#define FNC_UNRATIO
vec2 unratio (in vec2 st, in vec2 s) { return vec2(st.x, st.y*(s.x/s.y)+(s.y*.5-s.x*.5)/s.y); }
#endif
Use:
ratio(float2 st, float2 st_size)
#ifndef FNC_UNRATIO
#define FNC_UNRATIO
float2 unratio (in float2 st, in float2 size) {
return float2(st.x, st.y*(size.x/size.y)+(size.y*.5-size.x*.5)/size.y);
