#2515: drawTiles() sets tileScreenInfo[i][j].y values which do not exactly
correspond to rendered tiles

---------------------+-------------------------------------
When clicking on a tile, sometimes it thinks another tile was clicked on,
as if the mouse was slightly higher than it really was.
To see this, put down a checkerboard of rearming pads, deselect anything
in order to have the arrow cursor, and use this patch to constantly see
(in the terminal) which tile it thinks the mouse is over, and what the
corresponding tileScreenInfo[i][j] values of the corners of the tile are.
"mouseXY = (%d,%d), quad = (%d,%d),(%d,%d),(%d,%d),(%d,%d)" is in actual
pixels, "mousePos = (% 8.3lf,% 8.3lf)" is in map coordinates
