| 149 [12:00am] slouken: I was trying to see if it was possible to make a pluggable blit API, but I was going insane with trying to figure out how to make it fast. | 149 [12:00am] slouken: I was trying to see if it was possible to make a pluggable blit API, but I was going insane with trying to figure out how to make it fast. |

| 154 TODO | |
| 155 ---- | |
| 156 Change textures to static/streaming. Static textures are not lockable, | |
| 157 streaming textures are lockable and may have system memory pixels available. | |
| 158 SDL_compat will use a streaming video texture, and will never be HWSURFACE, | |
| 159 but may be PREALLOC, if system memory pixels are available. | |
| 160 | |
| 161 The software renderer will be abstracted so the surface management can be | |
| 162 used by any renderer that provides functions to copy surfaces to the window. |
