Major Changes

@invariant Warning

When using CompareFunction::Equal or CompareFunction::NotEqual on a pipeline, there is now a warning logged if the vertex
shader does not have a @invariant tag on it. On some machines, rendering the same triangles multiple times without an
@invariant tag will result in slightly different depths for every pixel. Because the *Equal functions rely on depth being
the same every time it is rendered, we now warn if it is missing.

-@vertex
-fn vert_main(v_in: VertexInput) -> @builtin(position) vec4<f32> {...}
+@vertex
+fn vert_main(v_in: VertexInput) -> @builtin(position) @invariant vec4<f32> {...}

Surface Alpha and PresentModes

Surface supports alpha_mode now. When alpha_mode is equal to PreMultiplied or PostMultiplied,
the alpha channel of framebuffer is respected in the compositing process, but which mode is available depends on
the different API and Device. If don't care about alpha_mode, you can set it to Auto.

SurfaceConfiguration {
// ...
+ alpha_mode: surface.get_supported_alpha_modes(&adapter)[0],
}

The function to enumerate supported presentation modes changed:

- pub fn wgpu::Surface::get_supported_modes(&self, adapter: &wgpu::Adapter) -> Vec<PresentMode>
+ pub fn wgpu::Surface::get_supported_present_modes(&self, adapter: &wgpu::Adapter) -> Vec<PresentMode>

Updated raw-window-handle to 0.5

This will allow use of the latest version of winit. As such the bound on create_surface is now RWH 0.5 and requires
both raw_window_handle::HasRawWindowHandle and raw_window_handle::HasRawDisplayHandle.

GLES

Changes

General
