Hover used a Blizzard minimize-button highlight, which read as a red
tint over the pin art and looked nothing like the map. The pins draw
their hover and pressed states from the same UI-QuestPoi-NumberIcons
atlas they draw everything else from, additively blended, so mirror
those cells alongside the ones already being copied.
Add the pressed offset the pins have, nudging the digit or the "?" a
pixel down and right while held, reset on redraw since the pool recycles
buttons and a line can be rebuilt with the mouse still down. Play the
sound the pins play as well: we call WorldMapFrame_SelectQuestFrame
directly, and the sound lives a level above it in WorldMapQuestPOI_OnClick.
