Apply transformation matrix to texture coordinates.

SurfaceTexture provides transformation matrix which should
be used to transform texture coordinates before sampling
to account for possible coordinate differences in the
underlying native buffer.

This was causing the texture to be flipped when rendered.
Also fix the square coordinates which caused stretching.
