Hey there! I was writing scrolling pane for myself and stuck onto your code while searching for minecraft forge and glScissor.

So instead of figuring out the scale of the screen, you can determine first the ratios:

int rx = this.mc.displayWidth / this.width;
int ry = this.mc.displayHeight / this.height;

And then multiply your rect's x, y, width and height by those ratios:

int w = 200;
int h = 200;
int x = width/2 - w;
int y = 80;

GL11.glScissor(x * rx, this.mc.displayHeight - (y + h) * ry, w * rx, h * ry);

That is another simpler (and better) way to glScissor in minecraft's GUI.

P.S.: Maybe you're already figured out (since this topic is over two years old), but I'm gonna do it anyway, since the code hasn't changed.

Thx for the gitignore
