Don't update all land texture when drawing tunnel (saves video throughput)

- Enable back console (doesn't render yet) - Make texture size be of power of 2

- Add alpha-channel to all sprites left - Reanimate ammo menu

- Save 8 MB of memory by freeing LandSurface and not using it anymore after game initialization - Reanimate girder (and partly teleportation tool)

Store Land surface in memory: - Fixes strange land texture disappering - Speed up operations, changing land after its initialization

Introduce UpdateLandTexture function to update just parts of surface

- Update land texture after explosions - Restore loading progress

Fix a bug introduced in previous revision (accidental delete of land surface)

Now game looks almost like it did before switching to OpenGL

Add alpha-channel to horizont sprites

More sprites are visible

Now hedgehogs are seen on map :)

Now land texture renders properly

Enable back fps counter

- Start conveting pngs to have alpha-channel

Enable water waves back

Respect alpha channel

Now show sprites too

Some further work on switching to OpenGL rendering

Start conversion to OpenGL rendering

Some changelog fixes

manual added
