Specifies a 4x4 transformation Matrix to apply in the vertex shader for each input frame.
The matrix is applied to points given in normalized device coordinates (-1 to 1 on x, y, and z axes). Transformed pixels that are moved outside of the normal device coordinate range are clipped.
Output frame pixels outside of the transformed input frame will be black, with alpha = 0 if applicable.

  - configure
```
default Size configure(int inputWidth,
                       int inputHeight)
```
    Deprecated.
    
    Configures the input and output dimensions.
    Must be called before getGlMatrixArray(long).
    
    Parameters:
    
    inputWidth - The input frame width, in pixels.
    
    inputHeight - The input frame height, in pixels.
    
    Returns:
    
    The output frame width and height, in pixels.
  - getGlMatrixArray
```
float[] getGlMatrixArray(long presentationTimeUs)
```
    Deprecated.
    
    Returns the 4x4 transformation Matrix to apply to the frame with the given timestamp.
  - toGlShaderProgram
```
default SingleFrameGlShaderProgram toGlShaderProgram(Context context,
                                                     boolean useHdr)

```
    Deprecated.
    
    Description copied from interface: GlEffect
    
    Returns a GlShaderProgram that applies the effect.
    
    Specified by:
    
    toGlShaderProgram in interface GlEffect
    
    Parameters:
    
    context - A Context.
    
    useHdr - Whether input textures come from an HDR source. If true, colors will be in linear RGB BT.2020. If false, colors will be in linear RGB BT.709.
    
    Throws:
    
    VideoFrameProcessingException - If an error occurs while creating the GlShaderProgram.
