removed UV bounds check

say we have a tri with 3 verts that have these uvs: [0.9, 0.95], [0.95, .9], [1.05, 1.05] Currently nexus will adjust those UVs to be [0.9, 0.95], [0.95, .9], [0.05, 0.05] Which will look like we are dealing with a tri that spans most of the texture, which is incorrect

Here is the sample texture generated by nexus. Notice thin strips of data on the right and top edges. Our input texture was 8192 and we have a mesh that has UV coords slightly out of bounds.
