| 3 """This examples demonstrates a simplish water effect of an | |
| 4 image. It attempts to create a hardware display surface that | |
| 5 can use pageflipping for faster updates. Note that the colormap | |
| 6 from the loaded GIF image is copied to the colormap for the | |
| 7 display surface. | |
| 8 | |
| 9 This is based on the demo named F2KWarp by Brad Graham of Freedom2000 | |
| 10 done in BlitzBasic. I was just translating the BlitzBasic code to | |
| 11 pygame to compare the results. I didn't bother porting the text and | |
| 12 sound stuff, that's an easy enough challenge for the reader :]""" | |
