Most of these were just converting char* into std::string back and
forth; some more used ReadUTF8, which was converted to use nicer
STL-style iterators over UTF-8 text.
The remaining ones are:
* arguments to Expr::From, which we'll change when refactoring
the expression lexer;
* arguments to varargs functions, which we'll change when adding
localization (that requires custom printf-style functions to
allow for changing argument order);
* arguments where only string literals are ever passed, which
are OK;
* in platform-specific code, which is OK.
In my (whitequark's) experience this warning tends to expose
copy-paste errors with a high SNR, so making a few fragments
slightly less symmetric is worth it.
Also mollify -Wlogical-op-parentheses while we're at it.
This font is less complete than our bitmap font, Unifont: Unifont
has essentially complete Unicode coverage and LibreCAD's font only
has Latin, Cyrillic and Japanese, but it can be extended rather
easily, so this should be fine for now.
These embedded fonts fatten glhelper.o quite a bit:
bitmapfont.table.h is about 8M in gzip-compressed bitmaps and
vectorfont.table.h is about 2M in raw vector data.
In spite of that it takes just around five seconds to build
glhelper.c on my laptop, so it should be fine.
The final executable grows from about 2M to about 8M, but this
is a small price to pay for fairly extensive i18n support.
The new font has somewhat different metrics, so the rendering
code has been fudged to make it look good.
Now it is possible to give non-ASCII names to groups
as well as see non-ASCII filenames of imported files.
In the future this makes localization possible.
This works for LTR languages, such as European and CJK,
but not RTL such as Arabic. Does Arabic even exist in
monospaced form? I have no idea.
After this change, SolveSpace does not contain nonfree assets.
Additionally, Perl is not required for the build.
Note that in the US, case law suggests that copyright does
not apply to bitmap fonts:
http://www.renpy.org/wiki/renpy/misc/Bitmap_Fonts_and_Copyright
Nevertheless, it was prudent to replace the asset with something
that is unambiguously free.
Some extra code is necessary to determine that the back faces
should not be drawn in red for transparent solids. It is expected
that the user will first ensure that the shell is watertight
and then set the opacity; back faces are still drawn if
the opacity is exactly 1.
The savefile format is changed backwards-compatibly by stashing
the alpha value in uppermost byte of 4-byte hex color value
in Surface and Triangle clauses. The existing files have 00
in the high byte, so RgbColor::FromPackedInt treats that
as "opaque".
This is required to avoid name conflicts with the Cocoa libraries
on OS X.
I renamed the `class SolveSpace` to `class SolveSpaceUI`, because
that's what it does, and because otherwise the namespace would
have to be called something else than `namespace SolveSpace`.
However, don't use ssglLineWidth for UI drawing operations.
These only draw horizontal or vertical lines that don't need to
be antialiased, and thus don't require the workaround. In fact
the workaround would make them thicker than needed.
Microsoft defines an RGB() macro that at one point was compatible with our
version (returning a packed integer containing 8-bit red, green and blue
channels), but is no longer, and the incompatibility led to an awkward
situation in w32main.cpp where we had to restore Microsoft's form of the
macro in order for the commctrl.h header to compile. By renaming the macro
to RGBi()---analogous to the RGBf() macro we already define---we avoid the
hassle entirely.
The SolveSpace top-level directory was getting a bit cluttered, so
following the example of numerous other free-software projects, we move the
main application source into a subdirectory and adjust the build systems
accordingly.
Also, got rid of the obj/ directory in favor of creating it on the fly in
Makefile.msvc.
