Questions About Graphical User Interfaces

[Mudbill]

I'm bored, so I just wanna ask and see if anyone at all knows anything about this.

Why is Amnesia's GUI slightly scaled down? I'm messing around with a fully custom GUI for a mod (I don't plan on releasing the mod, I just test things to see how much I can modify), and I've noticed that the files aren't drawn in the same size as their .tga file is. I understand this is the case with the background of the main windows because it needs to fit the size of the window itself, but things like the cursor bug me a bit.

As an example, I drew a Windows Classic cursor in the .tga file for the cursor. In-game it appeared slightly smaller in scale. It is as if it's only 95% of the actual size, but it is enough to distort the image and blur the lines.

How the .tga file looks when I open it:


In-game:

This same thing happens with the HPL editors. It makes the whole thing feel unstable to me. I don't know, I just really like things to be accurate and smooth. I guess it's my OCD hitting my head.

In the GUI configs you can also define a so-called active_size="-1 -1". If anyone has been messing with it, are you able to actually explain what it does? I have tried different values but I don't understand the logic behind it. The cursor's size doesn't change, but some of the GUI components have unpredicable results.

I don't expect anyone to know why this is (apart from the ones who actually developed the rendering engine), but perhaps anyone have any thoughts?
