-- Framework for managing rendering over the map area. This function is intended

-- nothing should be rendered at that position, the function should return nil.

-- screen coordinates). The rect is intersected with the visible map viewport to

-- get the range over which get_overlay_char_fn is called. If bounds_rect is not

-- specified, the entire viewport is scanned.

-- function MyMapOverlay:onRenderFrame(dc, rect)

-- local function get_overlay_pen(pos)

-- if safe_index(self.overlay_map, pos.z, pos.y, pos.x) then

-- return COLOR_GREEN, 'X', dfhack.screen.findGraphicsTile('CURSORS', 4, 3)
