This backports the work in #7815 and the subsequent fixes in #8393
The following program now works as expected in this branch in both
release_debug and debug mode:
```gdscript
print(sqrt(-1))
print(sqrt(-1))
var simple1=asin(10.0)
var simple2=acos(10.0)
print(simple1)
print(simple2)
```
And successfully prints -nan 4 times
This fixes#9580 and fixes#8925
This one allows for complex shaders paired with a simple lighting shader to skip code that would otherwise be pointlessly (and wastefully) run during the light pass.
You can use `if (AT_LIGHT_PASS) , negated or not, and that will be converted to a preprocessed #if when the shader is compiled.
Depending on your game (number of items and lights), this can be a *significant* performance gain, or at least avoids relying on the driver's optimizing abilities.
- 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.
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!

Done with `autopep8 --select=E7`, fixes:
- E701 - Put colon-separated compound statement on separate lines.
- E702 - Put semicolon-separated compound statement on separate lines.
- E703 - Put semicolon-separated compound statement on separate lines.
- E711 - Fix comparison with None.
- E712 - Fix (trivial case of) comparison with boolean.
- E713 - Fix (trivial case of) non-membership check.
- E721 - Fix various deprecated code (via lib2to3).
The reordering of the SConscript includes allows to ensure that
stuff like the builtin zlib headers will be available for libpng.
Also moved glew back into global env, otherwise windows seems
not to find it... Kind of shooting in the dark with this multi-env
setup.

* Shadow fadeout exponent hardcoded for now, should be user configurable.
* optimization - skip shadows outside visible range
(cherry picked from commit 0b12ebba11)
If "glFramebufferTexture2D()" fails on old drivers the Vector is empty.
Don't allow to read from empty Vector (NULL pointer).
(cherry picked from commit 7b8fe97888)
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
(cherry picked from commit a27fafb273)
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.
(cherry picked from commit b69e422af9)
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.
-Rearrange favorites in fs dock with drag and drop
-Removed import -> sub-scene, moved to scenetree contextual menu
-Removed import -> re-import , moved and integrated to FS dock
-Added ability in FS dock to re-import more than one resource
simultaneously
-Added ability to drag from native filesystem explorer to Godot, only
works on Windows though
-Removed scene reimport merge options, never worked well. Eventually
merging materials should be re-added
-Added ability to set custom root node type when importing scenes
-Re-Import is now automatic, can be configured back to manual in editor
settings
-Added resource previews in property list for many resource types
