return err
}
s.lastProgram = zeroProgram
s.lastProjectionMatrix = nil
s.lastColorMatrix = nil
s.lastColorMatrixTranslation = nil
if s.arrayBuffer != zeroBuffer {
context.DeleteBuffer(s.arrayBuffer)
}
if s.indexBufferQuads != zeroBuffer {
context.DeleteBuffer(s.indexBufferQuads)
}
if s.programTexture != zeroProgram {
context.DeleteProgram(s.programTexture)
}
