"replace" means "blit the image pixels as is", no matter what the
alpha value: if a pixel is RGBA=(1,1,1,0), it is written as is in the
frame buffer

Related to all of this, if I specify a blend mode of "Replace" for
my billboard's image, should that image be rendered now matter what
its alpha value is (including an alpha of 0.0) i.e. does "replace"
effectively mean no blending should occur?
If replace means no blending then I think there's a problem. If my
image has an alpha of 0 then it won't show.
