1.1.318a25

• Fixed bug with the Rectangle class's copy() function not creating a copy of the position lists and just creating a
  new reference

• Fixed bug with the Colour class's __eq__() and __nq__() functions raising an AttributeError when comparing
  against a non-Colour object

• Fixed the hex_to_rgb() and _hex_to_rgb() functions to return a tuple, not generator

• Fixed bug with the hex_to_hsl() and hex_to_hsv() functions both returning CMYK values

• Created new colour converter testing functions

• Changed Window __repr__() function to use "Window" and not "GraphWin"

• Renamed the Window is_resizable(), is_width_resizable(), and is_height_resizable() to use get instead

• The Window get_resizable() function now returns a tuple not a list

• Removed the Window __str__() function since __repr__() defined the same thing

• Added Window getter function testing functions

• Fixed bugs with all the CMYK colour conversion functions

• Changed the GraphicsError in the Window's __check_open() function to include the string "GraphicsError" at the
  start and return True if the window is open

• Added _check__check_open() and _check__autoflush() methods to the Window class to check the functionality of
  private methods

• Removed the Window start_move() and stop_move() methods until I can figure out what they do

• Removed the Window draw_bounds() function because it wasn't required.

• Fixed the Window get_pos(), get_x_pos(), and get_y_pos() functions to return the value relative to 0, 0

• Replaced all instances of the deprecated Point class usages with lists in Window.py

• The Window set_background() method no longer uses styles

• Changed Window get_bk_colour() method to get_background() to be consistent with the setter

• Window background colours can not be inputted as hex strings

• Removed all auto-flush checks in the Window methods because its private method __autoflush() also does that

• Renamed the variable RELIEF to BORDER_RELIEFS

• The Window set_icon() method now accepts icons in the local folder too

• Added 3 getter methods to the Window class: get_draggable(), get_x_draggable_x(), get_y_draggable()

  get_bottom_left(), and get_center()

• Fixed bug with the GraphicsObject get animation time left functions raising a TypeError

• Fixed error with the Text clone() method trying to clone a None type bounds object

• Added 5 getter methods to the _BBox classes: get_top_right(), get_top_left(), get_bottom_right(),
  get_bottom_left(), get_left(), get_right(), get_bottom(), get_top()

• Fixed the colour definition of DARKISH_TURQUOISE from a purple colour to a turquoise colour

• Internally changed how the button Button class keeps a track of its current state (normal, hover, or clicked)

• Redefined the _update_lasttime variable which was removed for an unknown reason

• Renamed the base colour conversion functions, like _rgb_to_hex() to rgb_to_hex_nocheck()

• Added a __version__ variable that keeps track of the goopyplib version, and an __all__ variable

• Added American (spelled with color) colour conversion tests to goopylib_tests.py

• Renamed the goopylib math subpackage to maths to avoid conflicts with Python's standard library

• Removed 'x_cursor' from CURSORS and moved it to CURSORS_WINDOWS since it isn't available on MacOS
