Use OpenGL 3.3 core profile instead of compatibility profile
- Rename OpenGL to GLES3 in the source code per community feedback.
  - The renderer is still exposed as "OpenGL 3" to the user.
- Hide renderer selection dropdown until OpenGL support is more mature.
  - The renderer can still be changed in the Project Settings or using
    the `--rendering-driver opengl` command line argument.
- Remove commented out exporter code.
- Remove some OpenGL/DisplayServer-related debugging prints.

Rémi Verschelde 386968ea97 Remove obsolete GLES3 backend
Due to the port to Vulkan and complete redesign of the rendering backend,
the `drivers/gles3` code is no longer usable in this state and is not
planned to be ported to the new architecture.

The GLES2 backend is kept (while still disabled and non-working) as it
will eventually be ported to serve as the low-end renderer for Godot 4.0.

Some GLES3 features might be selectively ported to the updated GLES2
backend if there's a need for them, and extensions we can use for that.

So long, OpenGL driver bugs!

Happy new year to the wonderful Godot community!

We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.

Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.

azagaya b835868067 Create shadow_vec for altering shadow computation
In 2.1 and 3.0, light_vec could be modified for altering shadow_computations.
But it broke shadows when rotating light. shadow_vec would do the same, but without breaking
shadows in rotated lights if not used.

Add inverse light transformation to shadow vec, so it's not affected when rotating lights;

Added usage define for shadow vec.

For shadow vec working properly when rotating a light, it's needed to multiply it by light_matrix normalized. Added usage define in order to don't do that if shadow_vec not used.

Hein-Pieter van Braam d308eb091a Fix many asan and ubsan reported issues
This allows most demos to run without any ubsan or asan errors. There
are still some things in thirdpart/ and some things in AudioServer that
needs a look but this fixes a lot of issues. This should help debug less
obvious issues, hopefully.

This fixes #25217 and fixes #25218

Rémi Verschelde 7b081a7fc8 Fix warnings about unhandled enum value in switch [-Wswitch]
Fixes GCC 5 warnings of the form:

core/io/http_client.cpp:288:9: warning: enumeration value 'STATUS_SSL_HANDSHAKE_ERROR' not handled in switch [-Wswitch]
core/io/marshalls.cpp:806:9: warning: enumeration value 'AABB' not handled in switch [-Wswitch]

Those can be trivial cases where adding a default fallback is the solution,
or more complex issues/hidden bugs where missed values are actually meant
to be handled.

Keeping track of discard
2018-08-08 09:54:59 -03:00
David Sichma c101dd5fa6 Keeping track of discard
Shader compilation now keeps track of the discard key word.

Previously only variables were monitored. But discard, which needs
special treatment in some cases, went unnoticed by the compiler as
discard is not a variable but a flow control.

This commit adds monitoring for discard.

Hein-Pieter van Braam 0e29f7974b Reduce unnecessary COW on Vector by make writing explicit
This commit makes operator[] on Vector const and adds a write proxy to it.  From
now on writes to Vectors need to happen through the .write proxy. So for
instance:

Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;

Failing to use the .write proxy will cause a compilation error.

In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.

_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.

Rémi Verschelde 00dfc9c8eb Shader lang: Properly assign INSTANCE_ID to gl_InstanceID
Note that gl_InstanceID is not supported in OpenGL ES 2.0,
so in the gles2 backend we assign it to 0.

Also clean up some duplicates/commented out code.
Fixes #20088.

karroffel bb655856e2 using TIME in light shader enables uses_fragment_time
The GLES3 shader compiler performs certain checks to enable or disable
the usage of certain uniform variables (and with that the set-up of UBOs).

If the `TIME` variable gets used inside the `vertex` function then the
renderer knows that it has to insert that value into the UBO.
The same applies to the `fragment` function.

The `light` function gets executed inside the fragment shader for every
light source that is relevant to the current pixel. If the `TIME` variable
gets used in that function then it needs to be present in the fragment-UBO.
The check for this was missing, so if a shader uses `TIME` inside `light`
but not inside `fragment` then the uniform will not actually be set up.
