A LavishGUI 2 Brush is used to "paint" something, so to speak. A Brush consists of a color, an optional image file, and an optional pixel shader.

Defining a Brush

A Brush is defined by a JSON object enclosed by {}.

Brush properties
color A Color definition. If not given, the default is [1.0, 0, 0, 0], although note that this may be overriden by a Template.
imageFile An image filename. If not given, no image file is used.
imageFileTransparencyKey A Color definition specifying the Transparent color of the image file. If not given, the default is [0, 0, 0, 0]
imageOrientation A string or array of strings indicating "normal" "mirrorHorizontal" and/or "mirrorVertical". These transforms will apply to the image.
pixelShader A Pixel Shader definition. The pixel shader provides the final color for each pixel, given the color and the image (if given) and other pixel shader-y things.
vertexShader A Vertex Shader definition.
