Be able to capture using the com.sun.opengl.utils.Screenshot with an alpha value

Inside the readToBufferedImage method change:

BufferedImage image = new BufferedImage(width, height,BufferedImage.TYPE_3BYTE_BGR);

to

BufferedImage image = new BufferedImage(width,
height,BufferedImage.TYPE_4BYTE_ABGR);

And 

gl.glReadPixels(0, 0, width, height, GL.GL_BGR,
GL.GL_UNSIGNED_BYTE,ByteBuffer.wrap(((DataBufferByte)image.getRaster().getDataBuffer()).getData()));

to

gl.glReadPixels(0, 0, width,
height,GL.GL_ABGR_EXT,GL.GL_UNSIGNED_BYTE,ByteBuffer.wrap(((DataBufferByte)image.getRaster().getDataBuffer()).getData()));

Added variants to all screenshot functions taking boolean alpha. Rewrote
original entry points in terms of new ones passing false for alpha parameter.
