For the time being we don't support writing a description for those, preferring having all details in the method's description. Using self-closing tags saves half the lines, and prevents contributors from thinking that they should write the argument or return documentation there.

|
Casts light in a 2D environment. Light is defined by a (usually grayscale) texture, a color, an energy value, a mode (see constants), and various other parameters (range and shadows-related).
|
|
[b]Note:[/b] Light2D can also be used as a mask.
