BUR #21379 has been rejected.
create alias anime_screencap -> anime_screenshot
create alias screencap_redraw -> screenshot_redraw
create alias screencap_background -> screenshot_background
create alias screencap_inset -> screenshot_inset
In terms of terminology there may be an argument for screencap
being used for partial screenshots, but I don't think that's a worthwhile distinction to make, and right now the naming feels uncoordinated.
