I am trying to use DrawBox/Line to draw a grid that will scale to varying resolutions.
So i Draw a box to cover the screens resolution and then draw lines across and down the screen then use GetImage() to create a sprite

Here's the problem;
It appears that drawing the lines doesn't draw a line but draws transparency through the box.
If you look at the code the lines should be red but they end up being the colour of the background. It's very weird!

replacing this part of code and the lines appear red

I think doing it the other way it only works with the makecolor(r,g,b) command
for example print(MakeColor(200,0,0)) will display -16777016 so the hexadecimal
equivalent is -ffff38 which I don't think can be represented in AppGameKit with the color
commands

That would work, too.

DrawBox(0, 0, w, h, 0xff909090, 0xff909090, 0xff909090, 0xff909090, 1)
DrawLine(i, 0, i, h, 0xff0000ff, 0xff0000ff)

The first 8bits (from left) are the alpha values
