The misterious windows networking stack...
Using connect instead of WSAConnect causes socket error 10022 under
certain conditions.
See: https://github.com/godotengine/webrtc-native/ (issue 6)
Having to guess, code path for connect is different then WSAConnect with
NULL extra parameters.
The only reference about weird error with this code mentions something
called "Windows Filtering Platform" but windows internals are, as
always, obscure.
This might be something to try and report to Microsoft if anyone has the
time to spare with the likely outcome of being ignored.
While OpenGL ES 3.0 and WebGL 2.0 both support non power-of-2 (NPOT)
textures in their specification, the situation seems to be less clear
about *compressed* NPOT textures using repeat or mipmap flags.
At least Chrome on Linux doesn't seem to support this combination,
and a variety of mobile hardware have similar limitations.
As a workaround, we force decompressing such textures when running on
WebGL 2.0, at the cost of loading time and memory usage.
Fixes#33058.
OpenGL uses the diamond exit rule to rasterize lines. If we don't shift
the points down and to the right by 0.5, the line can sometimes miss a
pixel when it shouldn't. The final fragment of a line isn't drawn. By
drawing the lines clockwise, we can avoid a missing pixel in the rectangle.
See section 3.4.1 in the OpenGL 1.5 specification.
Fixes#32279
On Unix systems, file descriptors are usually shared among child
processes.
This means, that if we spawn a subprocess (or we fork) like we do in
the editor any open file descriptor will leak to the new process.
This PR sets the close-on-exec flag when opening a file, which causes
the file descriptor to not be shared with the child process.
On Unix systems, sockets are like file descriptors, and file descriptors
are usually shared among child processes.
This means, that if we spawn a subprocess (or we fork) like we do in the
editor, open file descriptors will leak to the new process.
This causes issue with sockets as they might remain open and bound
(listening) when the original process closes.
Fixes this error:

This fixes an issue that was fixed for gles3 in #31419 but not applied
to gles2. The fix consists of using a constant scale for cube_normal of -1.0
instead of -1000000. It results in broken panorama rendering on the
oculus quest (see https://github.com/GodotVR/godot_oculus_mobile/issues/29)
Although the backup USE_SKELETON_SOFTWARE skinning path is currently used when float texture is not supported, the default skinning path still fails when float texture is supported but GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS is 0, i.e. the device cannot read from texture during vertex shader. This PR adds the logic to activate the SKELETON_SOFTWARE path if either of these cases occur, preventing crashes on devices which have this combination of features.
