RenderMode was never supported by URP. Maybe it was planned to be added but I couldn't find anyone who knows anything about.
Instead we hide the field and remove documentation for it.

…form by the wrong string

UI is adding included/excluded platforms in the UI by NamedBuildTarget.

So for instance, "Switch" is obtained from BuildTarget.Switch.ToString(), but if we do NamedBuildTarget(BuildTarget.Switch) it returns you "Nintendo Switch".

This was including/excluding RP assets that were not supposed to match the call to the API of BuiltTarget extension

Manual backport of [this PR](https://github.cds.internal.unity3d.com/unity/unity/pull/50412) + [this PR](https://github.cds.internal.unity3d.com/unity/unity/pull/25910).

Tested on D3D11 and Vulkan. Works well, the wireframe is now rendered.
It also fixes an issue with the DepthCopy, that is happening since 21.3 is not using the Blitter code introduced in 2022 + the changes for this pass.

![Fix_21_3_Wireframe](https://media.github.cds.internal.unity3d.com/user/1911/files/80ebf77a-4dee-4bec-96b5-e63032e60b1c)

Jira: UUM-65513

Reproduction steps:
1. Create a VFX Graph
2. Show the control panel or the blackboard (use the buttons in the toolbar)
3. Dock the “graph” Window to the bottom of the UI (for instance with the console)

Expected result: Floating panel is visible
Actual result: Floating panel disappears

… when async

Backport of [49983](https://github.cds.internal.unity3d.com/unity/unity/pull/49983) for [UUM-70273](https://jira.unity3d.com/browse/UUM-70273)

From trunk PR:
"This PR applies multiple fixes to HDRP Screen Space Reflection:
- It removes the SSR lighting texture by reusing the SSR accumulation texture
- It adds a fence before async work, so they wait for resources to be cleared when it reuses pooled resources. This fixes flickering on some platform where graphics and async command buffer are more sensitive to missing fences.
- It changes the hit point texture and lighting texture clears to be async if the pass is async. Due to the new fence, it couldn't overlap with shadow rendering, but moving the clear to the same queue as the rest of the work, is more optimized and has no fence."

Backport for UUM-19101

The shader utility function Linear01DepthFromNear does not work for APIs with reversed Z buffer (all of our APIs except OpenGL/GLES). I changed the function into one that works and updated some comments in shader code.

```
float Linear01DepthFromNear(float depth, float4 zBufferParam)
{
    // Old:
    // return 1.0 / (zBufferParam.x + zBufferParam.y / depth);

    // New:
    #if UNITY_REVERSED_Z
    return (1.0 - depth) / (zBufferParam.x * depth + zBufferParam.y);
    #else
    return depth / (zBufferParam.x * depth + zBufferParam.y);
    #endif
}
```

… sizes

There is a graphical issue when resizing Reflection Probe box sizes on macOS. The issue comes from trying to draw in the Editor (either using `GL` commands or `DrawMeshNow`, for example) while the `Event.current.type != EventType.Repaint` causes graphical issues on Metal. This PR fixes that issue by guarding against this case when rendering the filled in box.

This PR fixes the compiler error, described in UUM-48035, when using `single` precision:

…der)

This PR backports the changes from #49172 to 2022.3

This backports the 2022.3 HDRP mipmap debug views fixes (https://github.cds.internal.unity3d.com/unity/unity/pull/50196) to 2021.3.
This PR is identical to the 2022.3 PR outside of 2 very minor elements:
- I've not backported [this commit](https://github.cds.internal.unity3d.com/unity/unity/pull/50196/commits/1a9fac5a131104805277e5a46de82c34130eaafc) from the 2022.3 PR because the behaviour of the `Terrain Texture` dropdown was, strangely enough, already correct in 2021.3.
- 1 conflict in `LitDataIndividualLayer.hlsl` and 1 conflict in `UnlitData.hlsl`: in summary, in both cases, the code to calculate the `alpha` is a bit different (simpler) in 2021.3, so we just make sure that the code moved into the `if (_DebugMipMapMode == DEBUGMIPMAPMODE_NONE)` block truly is from 2021.3 and not 2022.3...

Address a few issues with shader graph shader variant limit.

…om Function node's body field

This PR fixes https://jira.unity3d.com/browse/UUM-76270.

The Custom Function node's body field was difficult to use due to a combination of broken sizing and a lack of scrollbars. This fix prevents the body field from growing beyond the inspector width, ~~and enables horizontal/vertical scrollbars~~. **Note: TextField does not have scrolling support in 2021.3, so the scrollbar addition was not backported. Other ports are not affected**.

…ode in Render Graph

The main issue goes to the hash method generation that was used for identifying Render Graph resources. We used the most performant way but it was too many collisions. After a bit of research the decision is to use FNV-1a implementation as it's the same performance but much more reliable. There's still a possibility for collision but a probability should be much smaller.

This PR doesn't include SpeedTree9 changes as ST9 support is Unity6+.
It also doesn't include the SpeedTree shadergraph/subgraph improvements in the original PR to keep changes minimal and only fix the bugs.

This PR fixes an issue where some leftover shadow-rendering uniforms aren't properly cleared when using the `Unlit Draw Mode` in the scene-view, leading to some visible artifacts when sampling the empty shadow-map set for this mode.

… cbuffer

Shader Graph allows to declare properties in a global context. These properties can be set from script, globally to all shaders at the same time. (see [Shader.SetGlobalVector](https://docs.unity3d.com/ScriptReference/Shader.SetGlobalVector.html for instance)).
These global properties work fine when used with a regular ShaderGraph material, but not with VFX outputs that use ShaderGraph.
The reason is that we were grouping them in a structure with the other exposed properties, when these should be read directly from the constant buffer. Just changing the declaration in the shader makes it work fine.
