Add support for font weight and stretch selection when using system fonts.
Add function to get system fallback font from a font name, style, text, and language code.
Implement system font support for Android.
Use system fonts as a last resort fallback.
The loaders have been generated through hpvb's dynload-wrapper, although
they had to be heavily handpatched to workaround some already reported
issues with it. I added a note to each generated file to account for
that.
As GLAD uses X11 stuff directly, I had to define the GLAD_GLX_NO_X11
macro to not let do it that, and handle myself the display loading and
screen handling part myself, which wasn't that hard but it's still
something worth saying.
I plan to improve greatly the X11 backend (including this aspect) but,
as the release isn't that far and I'm also working on the Wayland
backend, this will do for now, I hope.
This is accomplished through the addition of a GLAD GLX loader in the
`thirdparty` directory.
This is another step towards a nice Wayland/X11 interoperation.
GLAD 1 creates unusable loaders for EGL, while the newly released GLAD 2
does not, so for consistency I thought that it would be a good idea to
uniform things beforehand. While it had some API changes some renames
were all that was needed and everything works like before, at least on
the Wayland branch.
I've kept the structure identical, although this new generator has quite
a few hefty features, such as a single header mode.
I've also added GLAD to `thirdparty/README.md`, but I haven't specified
that in the commit title because it's a very small "fix".
The exit code is initialized as EXIT_FAILURE to indicate failures during
startup. Closing the Game window via the window manager does not
change the exit code, so the program exists with EXIT_FAILURE.
This PR set the exit code to EXIT_SUCCESS when initialization was
successful just before starting the main loop.
On X11 we rely on ConfigureNotify event to update rendering context
window size, but we don't get such event when resizing
programmatically, only when done "manually" by resizing the window
etc.
Replace all TODO uses of `#warning` by proper TODO comments, and will open
matching bug reports to keep track of them.
We don't have a great track record fixing TODOs, but I'd wager we're even
worse for fixing these "TODO #warning" so we should prohibit this usage.
