GLJPanel/AWTGLPixelBuffer: Reused BufferedImage didn't account for row-stride (regression of b33bdf41cf53f37203643a8551bf5d94b42a8fab)

SingleAWTGLPixelBufferProvider w/ allowing row-stride reuses the AWTGLPixelBuffer and it's BufferedImage
even w/ different width.

This leads to distortion if using the BufferedImage unhandled.

GLJPanel also set GL_PACK_ROW_LENGTH to pixelBuffer.width, which leads to an 'out-of-bounds'
exception if ReadPixels is used w/ panelwidth and panelHeight.

++

Introduce AWTGLPixelBuffer.getAlignedImage(width, height) which returns an aligned
BufferedImage while reusing the DataBuffer.

GLJPanel fetches a new alignedImage if required.

This allows a more efficient single buffer usage as intended, w/o the need of copying data.
