I started adding things to a Draw namespace, but it somehow felt really
wrong seeing Draw::Rect and Draw::Bitmap, etc. So instead, let's rename
the library to LibGfx. :^)
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
This functon will draw an ellipse which is intersecting the corners of
the rect given. It is a very naive implementation, taking 200 samples of
points around the ellipse, and drawing straight lines between each of
these points.
The ellipses look good enough to me though!
Callers of draw_pixel() are not expecting it to apply translation since
they will have already done that themselves.
This was causing draw_line() with thickness>1 to have an offset applied
in case the painter was already translated.
Painter::draw_line() now has an optional "bool dotted" parameter that
causes it to only render every other pixel.
Note that this only works with horizontal and vertical lines at the
moment and we'll assert if called with dotted=true for a diagonal line.
Get rid of the dedicated Emoji class to make it easier to store a null
value signifying a failed lookup.
This allows us to remember failed lookups, making subsequent failures
for the same codepoint much faster. :^)
Also change the API to take a destination rect instead of a source rect
since internally it was basically creating a destination rect from the
source rect anyway. It was a little confusing.
From here on, all strings displayed to the user are expected to
be encoded as UTF-8. The next few commits will deal with a few
existing places where this requirement is currently violated.

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. :^)
