About this sample
Move the person under falling blocks. The background turns red only when opaque pixels of
the two sprites overlap. Their rectangular bounds can overlap while the visible shapes miss.
The sample reads the original texture pixels through Texture2D.GetData and tests
the shared area, pixel by pixel.
