Bug detailed description:
--------------------------
create a 2D texture with border, and apply it to a QUARDS
clean color buffer
then create a 3D texture, with border color set to green, and apply it to a new
QUARDS. since the GL_TEXTURE_WRAP_S is set to GL_CLAMP_TO_EDGE, the left/right
edge should not use the color of border
But it turns out, the QUARDS is drawn as a triangle, which is wrong.
Reproduce steps:
----------------
start X
compile and run attached test case
Current result:
----------------
a triangle is drawn
Expected result:
----------------
QUARDS is drawn correctly
and the left/right edge should not use the color of border
