58366ce64d internal/glfw: make the file operation atomic 
If multiple Ebiten processes start at the same time, the file operation
can cause a race condition. Add a file lock to avoid this.

566957dc1c internal/graphicsdriver/metal: invert Y at the vertex shader 
Instead of using a negative height in the viewport, invert the Y direction
at the vertex shader. This is a little more readable as a negative height
is hacky.

This is a preparation for DirectX 12. DirectX 12's coodination system
is very similar to Metal, but doesn't treat a negative height in its
viewport unfortunately.

ebiten: provide SetScreenFilterEnabled, a way to disable the default screen filter (#1997)

examples/blur: fix the blur filter example to be a real box blur. (#2000) 
Also add a note that this is not how games should implement a blur if avoidable.

Krita's blur and the original blur:

The original image and the new blur (Krita's): 
https://rm.cloudns.org/img/uploaded/bd04828baf6c01fcf7301a6672a4c406.png

Note how Ebiten's blur has almost no vertical component.

Note how after the change it looks basically like Krita's.

Pre-failing test for color interpolation during rendering. (#2001) 
Before #1996, this failed with:

image_test.go:1997: At(1, 0): got: {64 64 128 255}, want: {0 128 128 255}

The difference is:

- Before, colors were interpolated in straight-color space:
  - Background: {0 0 255 255}
  - Vertex A: {255 0 0 0}
  - Vertex B: {0 255 0 255}
  - Interpolated: {128 128 0 128}
  - Premultiplied: {64 64 0 128}
  - Onto Background: {64 64 128 255}
- After, colors are interpolated in premultiplied space:
  - Background: {0 0 255 255}
  - Vertex A: {255 0 0 0}
  - Vertex A premultiplied: {0 0 0 0}
  - Vertex B: {0 255 0 255}
  - Vertex B premultiplied: {0 255 0 255}
  - Interpolated: {0 128 0 128}
  - Onto Background: {0 128 128 255}

This DIFFERS from the sample fragment shader, which returns the color as is
(Kage allows vertex color values to be used for arbitrary purposes and
interpolates independently):

- Shader sample:
  - Background: {0 0 255 255}
  - Vertex A: {255 0 0 0}
  - Vertex B: {0 255 0 255}
  - Interpolated: {128 128 0 128}
  - Onto Background: {128 128 128 255}

as the blend function is `GL_ONE` / `GL_ONE_MINUS_SRC_ALPHA`. This shader behavior
is unchanged but has been documented by #1996.
