| Version 1.0: first public release. |
| Version 1.1: fixed bug to set *error to FLI_OK when returning successfully from FLI_Open |
| added function FLI_Reset to reset the animation to the first frame |
| Version 1.2: added function FLI_Skip to skip the current frame without rendering |
| FLI_Animation->surface is now correctly locked and unlocked |
| the rwops stream is now part of the FLI_Animation structure and is closed inside FLI_Close |
| renamed FLI_Reset to FLI_Rewind |
| added function FLI_Version that returns the library version |
