Functions
Animation	Pong (unsigned offset, unsigned width, unsigned height, unsigned ballSize, bool rainbow, frc::AddressableLED::LEDData ballColor, frc::AddressableLED::LEDData backgroundColor, units::millisecond_t frameTime, argos_lib::led::PanelScanParams scanParams)
	Animation that kind of works like a DVD player screensaver (https://youtu.be/QOtuX0jL85Y). A ball bounces around the panel changing color.
AnimatedSprite	ChompingPacMan (float radius, frc::AddressableLED::LEDData color, units::degree_t direction, units::millisecond_t chompPeriod, bool feathered=false)
AnimatedSprite	DyingPacMan (float radius, frc::AddressableLED::LEDData color, units::degree_t direction, units::degree_t initialMouthAngle, units::millisecond_t animationTime, bool feathered=false)
Animation	PacManPacing (unsigned offset, unsigned width, unsigned height, bool rainbow, frc::AddressableLED::LEDData pacManColor, argos_lib::led::PrimaryScanDirection paceDirection, units::millisecond_t chompPeriod, units::millisecond_t moveSpeed, argos_lib::led::PanelScanParams scanParams, bool feathered=false)
void	DrawRectangle (Panel &dest, unsigned rectWidth, unsigned rectHeight, float x, float y, frc::AddressableLED::LEDData color)
	Draws an axis-aligned rectangle to a panel. All pixels outside the rectangle are unmodified.
void	DrawCircle (Panel &dest, float radius, float x, float y, frc::AddressableLED::LEDData color, bool feathered=false)
	Draw a circle to the panel.
Sprite	DrawCircleSprite (float radius, frc::AddressableLED::LEDData color, bool feathered=false)
	Generate a sprite containing a circle with transparent background.
void	RenderSprite (Panel &dest, const Sprite &sprite, float x, float y, float alpha=1.0)
	Draw a sprite centered at a point to a panel. This will align the sprite to the nearest pixel alignment on the panel.
Sprite	DrawPacMan (float radius, frc::AddressableLED::LEDData color, units::degree_t direction, units::degree_t mouthAngle, bool feathered=false)
	Generate PacMan sprite :D.

Animation that kind of works like a DVD player screensaver (https://youtu.be/QOtuX0jL85Y). A ball bounces around the panel changing color.

Parameters

offset	Address of first LED in controlled panel
width	Width of panel in pixels
height	Height of panel in pixels
ballSize	Width and height of ball in pixels (it's a square... a circle would basically be the same at this size and I'm lazy)
rainbow	When true, ball changes to a random hue on every bounce!
ballColor	Initial color of the bouncing ball
backgroundColor	Background color behind the ball
frameTime	Time for ball to travel one pixel distance
scanParams	Parameters controlling the serialization of the internal panel to pixel addresses

Returns

Animation to use to control a panel with this animation pattern

RenderSprite()

void argos_lib::led::animation::RenderSprite	(	Panel &	dest,
		const Sprite &	sprite,
		float	x,
		float	y,

Parameters

dest	Panel to draw to
sprite	Sprite to draw
x	Horizontal center
y	Vertical center
alpha	Global sprite transparency where 0 is fully transparent and 1 is fully opaque
