flush_dirty()

void flush_dirty

(

void

)

Flush all regions that have been previously marked as dirty. See dirty_rect and dirty_all. This function is generally called after we've processed a batch of drawing operations.

update_unit_info_label()

void update_unit_info_label

(

struct unit_list *

Update the information label which gives info on the current unit and the tile under the current unit, for specified unit. Note that in practice punit is always the focus unit.

Clears label if punit is nullptr.

Typically also updates the cursor for the map_canvas (this is related because the info label may includes "select destination" prompt etc). And it may call update_unit_pix_label() to update the icons for units on this tile.
