glGetLight
params returns a single integer or floating-point value representing the linear
attenuation of the light. An integer value, when requested, is computed by rounding the
internal floating-point representation to the nearest integer. The initial value is 0.
GL_QUADRATIC_ATTENUATION
params returns a single integer or floating-point value representing the quadratic
attenuation of the light. An integer value, when requested, is computed by rounding the
internal floating-point representation to the nearest integer. The initial value is 0.
Notes
It is always the case that GL_LIGHTi = GL_LIGHT0 + i.
If an error is generated, no change is made to the contents of params.
