* Return a non-accelerated BufferedImage of the requested type with the

* with a SrcOver operation, otherwise make a SrcNoEa copy.
* <p>
* Returned BufferedImage is not accelerated for two reasons:
* <ul>
* <li> Types of the image and surface are predefined, because these types
* correspond to the TransformHelpers, which we know we have. And
* acceleration can change the type of the surface
* <li> Image will be used only once and acceleration caching wouldn't help
