Added a new version of the patch, which fixes s problem with Graphics2D output
(e.g. SVG --> PDF). PDFGraphics2D.addRenderedImage re-creates a
org.apache.xmlgraphics.image.loader.impl.ImageRendered instance, that can be
handled by the ImageRenderedAdapter. This is not nice, because the image loader
originally creates a org.apache.xmlgraphics.image.loader.impl.ImageRendered
instance, which is then lost because
ImageConverterBitmap2G2D.Graphics2DImagePainterImpl.paint() can only pass a
java.awt.image.RenderedImage instance. This problem is also visible when
PDFGraphics2D.addRenderedImage has to re-create the ImageInfo instance
(ImageInfo info = new ImageInfo(null, "image/unknown")). In order to fix that,
I wrap the org.apache.xmlgraphics.image.loader.impl.ImageRendered instance in a
new class (ImageRenderedG2D) that implements the java.awt.image.RenderedImage
interface and gives access to the original
org.apache.xmlgraphics.image.loader.impl.ImageRendered instance.
> [PATCH] Ignore ICC profiles added by ImageIO loader

>
> When rendering PNG files for PDF output, ICC profiles are taken into account
> which were added by the ImageIO loader. This causes an unexpected color
> display (light, dull colors) and should be avoided.
> This bug only applies to image files that don't have an embedded ICC profile
> and are loaded by ImageLoaderImageIO.
