We need to re-evaluate the BND constants, in Renderer.java, to improve the smoothness of non AA shape once RT-39424 is fixed.

Currently I have to tune the BND constants, in Renderer.java, to reduce the noisy jaggies. But it could simply an issue of RT-39424.

BND constants changed from
    private static final float DEC_BND = 20f;
    private static final float INC_BND = 8f;

to
    private static final float DEC_BND = 5f;
    private static final float INC_BND = 2f;

We might want to revert this back once we have a more accurate center pixel sampling.
Note: Similar is also made in the native Renderer.h for native Pisces implementation.
