This adds the unit, date-time, and palette histogram metadata properties for PNG images to GDI+. With these changes, the properties returned match Windows for all files in the PNG samples suite found at http://www.schaik.com/pngsuite/ .
-- v2: gdiplus: Set PNG palette histogram property when present. gdiplus: Set PNG date-time property when present. gdiplus: Set PNG unit properties always. gdiplus: Refactor png_metadata_reader. gdiplus/tests: Factor out check_properties functions.
