Set lights and also applies appropriate transformations on the positions and spot directions.

<source lang="c">
void GPU_set_basic_lights(int light_count, GPUbasiclight lights[]);
int GPU_get_basic_lights(GPUbasiclight lights_out[]);
</source>

Set lights without transforming position or spot_direction.
Suitable for restoring a backup copy of previous light state.
Keeps position and spot position from getting transformed twice.

<source lang="c">
void GPU_restore_basic_lights(int light_count, GPUbasiclight lights[]);
</source>

A white directional light shining straight down with no attenuation or spot effects.
Same as the default legacy OpenGL light number 0.

<source lang="c">
extern const GPUbasiclight GPU_DEFAULT_LIGHT;
</source>
