nick black b0915d1db6 Proper transparent blitter stacking ... This completes the work for #1068. This addressed a subtle issue. When we're using pixel->semigraphic art, we want slightly different rendering. Essentially, imagine that we have two images, each two pixels tall and one pixel wide. The top image is a transparent pixel above a white pixel. The bottom image is a white pixel above a black pixel. We'd expect the result to be two white pixels, but we can instead get a black pixel above a white pixel. This is because the *background* color is being merged from the bottom plane, but really we want the *top* color. Ncvisuals are now blitted along with information regarding which quadrants they draw over, and when appropriate, we invert the foreground and background. Closes #1068.		2021-02-02 00:57:58 -05:00
