Public Member Functions
	Light (Vec3f position, Vec3f direction, ColorR8G8B8 ambient, ColorR8G8B8 diffuse)
void	SetProjParams (Projection projection)
	Sets the projection parameters for lights that require a frustum (typically spot lights or shadow-casting lights).

Protected Attributes
Vec3f	m_Position
	World-space position of the light.
Vec3f	m_Direction
	Normalized world-space direction of the light. Used for directional and spot lights.
Vec3f	m_Up
ColorHSV	m_DiffuseColor
	Diffuse color contribution of the light. Defines the main visible light color.
ColorHSV	m_AmbientColor
	Ambient color contribution of the light. Used for low-frequency indirect lighting.

Detailed Description

Base light class used for all light types in the SystemEx.Drawing namespace. Provides shared parameters such as position, direction, diffuse/ambient color and projection settings. Specific light types (spot, point, directional) extend this class with additional behavior.
