I want to create a bitmap border ctrl with a one pixel wide border, to archieve a nice bevel effect on white style guis.
However, it does only seem to work with 2px wide borders.
Code that creates the profiles:
if(!isobject(StripeBorderProfile))
new GuiControlProfile(StripeBorderProfile : GuiBitmapBorderProfile) {bitmap = "Add-Ons/Client_ZGUI/images/stripeArray";hasbitmaparray = 1;};
if(!isobject(StripeBorderProfile2))
new GuiControlProfile(StripeBorderProfile2 : GuiBitmapBorderProfile) {bitmap = "Add-Ons/Client_ZGUI/images/stripeArray2";hasbitmaparray = 1;};
(I attached the images)
How they look in-game:
The one on the left is one pixel wide, the one on the right two.
Notice how the one pixel wide one is completely messed up and red.

I can't just use the 2px wide one because when I place a swatch in it so it overlaps it one pixel, nothing will happen, the swatch doesn't overlap it.
How can I archieve a one pixel wide bitmap border ctrl?
