update parameters in uploadToTexture() for GLES20

Google optimized the uploadToTexture with GLES3.0+,
This allows us to upload a sub-rectangle of texture,
but this has compliance issue with GLES 2.0.

With OpenGL ES 2.0 we need to copy the bitmap in a
temporary buffer if the stride doesn't match the width,
and then upload entire temporary stripes.
