LibGfx: Allow passing an ideal size to image decoders
...
The ideal size is the size the user will display the image. Raster
formats should ignore this parameter, but vector formats can use
it to generate a bitmap of the ideal size.

LibGfx: Return true from PortableImageDecoderPlugin::initialize()
...
Reading the two magic bytes are always done in `decode()` by calling
