WPF Image Drawing Problem - Now solved!!!!!

The latest .NET Framework October 2019 Preview of Quality Rollup has
fixed the problem. The problem was:

Software rendering fails to draw images whose position and scaling are
too large.

For example, an Image element with Width=10, sourced to a bitmap with
width=500 and positioned 700 pixels from the left edge of the enclosing
window, fails to appear because the scaling factor S = 500/10 = 50 and
the position X=700 are too large, in the sense that their product S * X
= 50 * 700 = 35000 exceeds 2^15 = 32768.
