I did something similar, using 3d vgui, but I was drawing a texture that was transparent, so the contents didn't have to be a power of two. The problem I had was that it was sampling the transparent parts from the edges, so there would be lines on the part of the texture that was transparent. I fixed it by setting the alpha of the first row and column to 0. Drawing with a mesh, or with 3d vgui, or even mat_filtertextures 0, it still applies some filtering.
