Allow to reconfigure stdin to read input keys, this process could lead to undesired effects. Use with care.

Disabled by default.

Added comments for the future

Load glTF

When using FormatText() several times in same function, returned string is static and so, the same is returned, resulting in failures on shader loading.

From the Clang documentation[1]:
> -x<language>, --language <arg>, --language=<arg>
> Treat subsequent input files as having type <language>

Follow the advice. Fixes #840.

This reverts #841 commit 97160fd970.

[build] fixed GLFW compiler flag for OSX

Contributed by ProfJski

Now shader uses `fragTexCoord` that are the full screen texture coordinates normalized, instead of `gl_fragCoord`, the unnormalized screen coordinates

Update julia set example.

Also changed path to shader back to what it was originally.

Now dividing by the zoom instead of multiplying (in the shader), so zoom works as expected. Also zoom increase/decrease is now scaled depending on the current zoom.

Note that all meshes are loaded as a single one at this moment, loading should be improved!

This reverts commit 4773de26a5.

which adds -lwinmm at the wrong place. It should be in the raylib
linker flags, not GLFW's.

extra-cmake-modules 5.38.0a is no longer hosted at the specified
kernel.org link. Use the occasion to move on to 5.58.

Because newer ECM debian packages have the control.tar file
xz-compressed, we need to update dpkg as well on trusty.
