描述

Originally created by @jhutar in #232

I have images dirt.png and bush.png and with this I can create temporary image on the fly when starting the game (so my actor do not need to draw two overlapping images when running the game):

import pygame.image
img_dirt = pygame.image.load('images/dirt.png').convert_alpha()
img_bush = pygame.image.load('images/bush_small.png').convert_alpha()
img_dirt.blit(img_bush, (0,0))
images.add('tmp_dirt_with_bush', img_dirt)
my_actor.image = 'tmp_dirt_with_bush'

Please let me know if it makes sense.

研究方向
Examine the image loading module in pgzero, likely in pgzero/loader.py, to understand how images are cached. The feature should allow adding a pre loaded Pygame surface to the cache via a method like `images.add(name, surface)`. Review the existing `images` object to see if it's a simple dictionary or has a class, and ensure the new method fits the API.
