We are clamping texture size to half similar to OpenGL with code :
// 7160609: GL still fails to create a square texture of this
                // size. Half should be safe enough.
                // Explicitly not support a texture more than 2^14, see 8010999.
                textureSize = textureSize <= 16384 ? textureSize / 2 : 8192;

Need to verify whether we need to do this or allow maxTexture size to be 16384
