This adds a function to draw a circle specified by a center point (
relative to the given Rect) and a radius. The circle arc is only drawn
inside the specified Rect as to allow for circle arc segments.
Technically this was already possible using draw_elliptical_arc(), but
the algorithm is quite involved and lead to wonky arcs when trying to
draw circle arc segments.
Previously <AK/Function.h> also included <AK/OwnPtr.h>. That's about to
change though. This patch fixes a few build problems that will occur
when that change happens.
This wasn't much of a problem before because copying the ByteBuffer
merely copied the RefPtr but now that ByteBuffer behaves like Vector
this causes unnecessary allocations.
The checkerboard pattern used in transparency backgrounds was sometimes
misaligned with the grid. This happened because it was incorrectly
anchoring the pattern to the clipped rect instead of the global
grid of the underlying paint target.
Matrix4x4 was defined as a derived class of Matrix<N,T> before.
Furthermore, some code was duplicated and it was overall just messy.
This commit turns Matrix4x4 into a simple alias for Matrix<4,T>.
Matrix elements were interpreted in different ways.
This makes it definitely row-major, allowing initialization via
initializer list in a standard scientific order. Also matrix
multiplication now happens in the correct order and accessing
elements happens as m_elements[row][column].
This cuts a region of a bitmap specified by the provided Gfx::IntRect
and returns it. Areas outside of the bounds of the original bitmap are
filled in with black.
We were not substituting the window modified marker ("[*]") in the
title strings we were sending to WM clients. This caused the Taskbar
to show pre-substitution window titles for the Text Editor application.
This patch moves the window title resolution to Window::compute_title()
which is then used throughout.
This commit adds a draw_physical_line method, which is the exact same
as draw_line, except it's parameters are already transformed and
scaled. This is used by both draw_line and draw_rect, as a slight
optimization to save some work. It also fixed draw_rect not checking
whether it should draw the lines before drawing them.
This allows the painter to be scaled separately in both directions, and
not just in integer intervals. This is crucial for proper SVG viewBox
support.
Most bitmap-related things verify the scale to be one as of now.
This commit unifies methods and method/param names between the above
classes, as well as adds [[nodiscard]] and ALWAYS_INLINE where
appropriate. It also renamed the various move_by methods to
translate_by, as that more closely matches the transformation
terminology.
This adds a *very* simplified version of the UNICODE BIDIRECTIONAL
ALGORITHM (https://www.unicode.org/reports/tr9/), that can render most
bidirectional text but also produces awkward results in a large amount
of edge cases, and as such, this should probably be replaced with a
fully spec compliant implementation at some point.
We had some inconsistencies before:
- Sometimes "The", sometimes "the"
- Sometimes trailing ".", sometimes no trailing "."
I picked the most common one (lowecase "the", trailing ".") and applied
it to all copyright headers.
By using the exact same string everywhere we can ensure nothing gets
missed during a global search (and replace), and that these
inconsistencies are not spread any further (as copyright headers are
commonly copied to new files).

Problem:
- `constexpr` functions are additionally decorated with `inline`
keyword. This is redundant since `constexpr` implies `inline`.
Solution:
- Remove redundancies.
This uses the per glyph width to determine if the glyph is actually
present in the font, and not just inside the range the font can covers
This means that characters that are in the font's range but that are
missing a glyph will show up as the missing character glyph instead of
being invisible.
This replaces the glyph width spinbox in the font editor with a
checkbox when editing fixed width fonts that indicates if the
currently selected character's glyph is present in the edited font
(For variable width fonts a non zero width implies presence)
This commit also changes the background color of glyphs in the glyph
map based on the presence of each specific glyph in the font.
Since we were always saving the glyph widths array to the font file, we
now also always load it, even on (which also simplifies the logic a bit)
fixed width fonts. We also set it initially to 0 instead of the default
fixed width, which allows us to use it to check for glyph presence in
both fixed width and variable width fonts.
