GL_LINE_LOOP

[chrs2021]

I noticed this isn't in the ds's implentation of openGL. I was wondering what could i use instead?

libnds only has polygon implementations that are already supported by the hardware, such as tris, tri strips, quads, and quad strips. Lines are supported via making tris with the 2nd and 3rd points the same for each groups of 3.
