Default clear phase which reset the main canvas with a color of {0,0,0,0}
All buffers, color, depth and stencil are cleared.
public void ClearPhase ()

param  output FBO to clear, if null default canvas will be cleared
public void ClearPhase (FBO output)


Clear phase which reset the main canvas.
param  clearColor not null, array of size 4, colors premultiplied
public void ClearPhase (float[] clearColor)


Clear phase which reset given fbo or main canvas.
param  output FBO to clear, if null default canvas will be cleared
param  clearColor not null, array of size 4, colors premultiplied
public void ClearPhase (FBO output, float[] clearColor)


Clear phase which reset given fbo or main canvas.
param  output FBO to clear, if null default canvas will be cleared
