Description
After the latest fixes for large images in NGImageView we now have stitching errors at their borders due to the fact that the Graphics.drawTexture() method does manual handling of the edge conditions on subimages by default.

We need a mechanism to allow a caller to tell the graphics method to avoid edge conditions for the edges that need to be stitched together accurately.

An ImageFragmentTest application is attached which can help reproduce the problem, but note that the maximum texture size would have to be hardcoded by changing the value in NGImageView to 64 in order to show the problem: final static int MAX_SIZE_OVERRIDE = 64; // 64
