333366a99d WindowServer+Taskbar: Send WM icon updates as Gfx::ShareableBitmap
Window icons in Taskbar were previously received in WM events with
shbuf ID's. Now that Gfx::ShareableBitmap is backed by anonymous files,
we can easily switch to using those.

56cad36ef2 LibGfx: Make Painter::draw_rect() scale-aware
Needed for the window server minimize animation.

draw_rect() can't just call draw_line() because that isn't
draw_op()-aware. The draw_op()-awareness in Painter looks a bit ad-hoc,
but that's for another day.

4d97b955e6 LibGfx: Allow creating a Gfx::Bitmap backed by an anonymous file
Gfx::Bitmap::create_with_anon_fd() creates such a Bitmap, and also
optionally takes ownership of the file, making sure to close() it
on destruction.

d551263b11 LibGfx: Make it possible to apply an (integer) scale to a Painter
This adds a scale factor to Painter, which will be used for HighDPI
support. It's also a step towards general affine transforms on Painters.

All of Painter's public API takes logical coordinates, while some
internals deal with physical coordinates now. If scale == 1, logical
and physical coordinates are the same. For scale == 2, a 200x100 bitmap
would be covered by a logical {0, 0, 100, 50} rect, while its physical
size would be {0, 0, 200, 100}.

Most of Painter's functions just assert that scale() == 1 is for now,
but most functions called by WindowServer are updated to handle
arbitrary (integer) scale.

Also add a new Demo "LibGfxScaleDemo" that covers the converted
functions and that can be used to iteratively add scaling support
to more functions.

To make Painter's interface deal with logical coordinates only,
make translation() and clip_rect() non-public.

545b4879e4 LibGfx: Make Painter::draw_pixel() with thickness = 1 work with RGBA
The underlying fill_rect() works correctly, but the special case for
thickness = 1 was not blending the new color with the target pixel's
color, causing RGBA colors to be painted as their RGB counterpart.
