add auto-scaling of UI depending on screen resolution - resolves #682

layout(location = 0) out vec4 diffuse;
in vec2 uvcoord;

uniform vec4 color;
uniform vec2 size;
#ifndef FILL
uniform float thickness;
#endif

void main(void) {
#ifdef FILL
    diffuse = color;
#else
    if (uvcoord.x < thickness || uvcoord.x >= size.x - thickness || uvcoord.y < thickness || uvcoord.y >= size.y-thickness) {
        diffuse = color;
    } else {
        discard;
    }
#endif
