If ARB_framebuffer_object is not supported, try to fall-back to
EXT_framebuffer_object if present.
In current version of godot, the way framebuffers are used is backward
compatible with the older EXT_framebuffer_object extension.
Fixes#6591
Done with SuperUserNameMan
The macro USE_LIGHT_SHADOW_COLOR actually was being defined when the shader used SHADOW (the output shadow color), not the shadow color set for the light so it's better named USE_OUTPUT_SHADOW_COLOR. In 3D there's not that difference but renaming as well for consistency.
- Add a proper function to retrieve IP addresses.
- Solve issues with Windows FileAccess and DirAccess to use the same code
for WinRT.
- Add patches to the GLES2 rasterizer to workaround ANGLE issues.
-Added anti-aliasing on lines
-Improved draw performance enormously
-Removed sequence ports for most nodes, current visual scripts will likely be broken now. Sorry!
The engine will still segfault, but the error message should be displayed by the
OS in a blocking manner, so that it will only crash once users have acknowledged
the error dialog.
Closes#1162.
The only differences we have with the upstream tarball are marked with
`// -GODOT-` comments for clarity. The changes we currently have are
just some defines for cross-platform configuration, and could likely be
moved to the SCons buildsystem (ideally in a sub-environment to avoid
having RtAudio-specific defines pollute the whole build log).
One change for WinRT was not kept, if it is needed it should ideally be
integrated upstream:
```
#if defined(__WINDOWS_DS__) || defined(__WINDOWS_ASIO__) || defined(__WINDOWS_WASAPI__)
-#ifdef WINRT_ENABLED
- #define MUTEX_INITIALIZE(A) InitializeCriticalSectionEx(A, 0, 0)
-#else
#define MUTEX_INITIALIZE(A) InitializeCriticalSection(A)
-#endif
```
Multi-character character constants are implementation defined,
and therefore they are risky to use for use when trying to be compatible
with so many different platforms. Fixes#2540.
Warning: libpng 1.6 is strict about iCCp chunks being incorrect,
solution is to fix the profile. On *nix ImageMagicks "convert" works
on windows optiPNG.
