Removed load_prepare nearly identical to ImageFile load_prepare

[radarhere]

Pillow/src/PIL/PsdImagePlugin.py

Lines 158 to 164 in 397a940

	def load_prepare(self):
	# create image memory if necessary
	if not self.im or self.im.mode != self.mode or self.im.size != self.size:
	self.im = Image.core.fill(self.mode, self.size, 0)
	# create palette (optional)
	if self.mode == "P":
	Image.Image.load(self)

is nearly identical to its super method

Pillow/src/PIL/ImageFile.py

Lines 280 to 286 in 397a940

	def load_prepare(self):
	# create image memory if necessary
	if not self.im or self.im.mode != self.mode or self.im.size != self.size:
	self.im = Image.core.new(self.mode, self.size)
	# create palette (optional)
	if self.mode == "P":
	Image.Image.load(self)

And the differences don't lead to any changes.

>>> from PIL import Image
>>> im = Image.core.fill("RGB", (1, 1), 0)
>>> Image.Image()._new(im).load()[0, 0]
(0, 0, 0)
>>> im = Image.core.new("RGB", (1, 1))
>>> Image.Image()._new(im).load()[0, 0]
(0, 0, 0)
