I have done it successfully in the past by modifying the texture transform. Remember we are talking about OpenGL ES 2.0 which has no texture borders and limits wrap mode for NPOT textures to CLAMP_TO_EDGE.

Pad it to a power-of-two and fudge the app-provided texture coordinates - admittedly not as easy with fragment shaders as it was with fixed-function texture transform matrices.
It's anything but easy. You can't simply "fudge" coordinates; that gets edge conditions wrong.
