Also add ImageDecoder APIs for controlling the volatile flag.

35c26a06fc LibCore: Move puff() from LibDraw to LibCore
Since it's used both by CGzip and PNGLoader, it seems most appropriate
to keep this in LibCore.

f970578cd4 LibDraw: Rename ImageLoader => ImageDecoder
ImageLoader was not the right name for this, as there is no loading
happening, only decoding. :^)

8acc61f19a LibDraw: Have the PNGImageLoaderPlugin remember if it failed to decode
Instead of trying again when asked repeatedly, just remember if it
didn't work out the first time.

1bd2941467 LibDraw: Add ImageLoader, a simple abstraction for image loading
An ImageLoader is a generic interface for loading encoded image data of
any supported format. It has an ImageLoaderPlugin internally that does
all the work.

This patch adds an initial PNGImageLoaderPlugin that knows how to
retrieve the size of a PNG, and the bitmap. The API is divided into
size() and bitmap() to facilitate geometry-only decoding.
This will be useful in places like LibHTML where we need dimensions for
layout purposes but can wait with the bitmap until later.

8f45a259fc ByteBuffer: Remove pointer() in favor of data()
We had two ways to get the data inside a ByteBuffer. That was silly.

aac8b091a4 LibDraw: Implemented support for more PNG formats (#614)
- Implemented support for more PNG formats including 16-bit per channel
  and 8-bit indexed with palette.
- Made the library a little more resistant to crashes by returning
  false for known but unsupported formats.

1c0669f010 LibDraw: Introduce (formerly known as SharedGraphics.)
Instead of LibGUI and WindowServer building their own copies of the drawing
and graphics code, let's it in a separate LibDraw library.

This avoids building the code twice, and will encourage better separation
of concerns. :^)
