c37ffecafd internal/graphicsdriver/metal: reorder uniform variables
This might improve memory allocations.

This makes the code more consistent with HLSL's packing rule [1]

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)
Using FilterNearest rather than filterScreen or FilterLinear speeds up a

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.

internal/atlas: optimization: send premultiplied alpha from vertex to fragment shader. (#1996)
Note that this applies only to the builtin shaders - interface for Kage stays
unchanged for compatibility.

Minor compatibility delta: when interpolating alpha values, previous code has
created nonsense values, such as, when interpolating from
fully-transparent-black (0,0,0,0) to opaque-white (1,1,1,1), something like
half-transparent-grey (0.25,0.25,0.25,0.5) where half-transparent-white
(0.5,0.5,0.5,0.5) is used by the new code.

I assume this is a strict improvement, however this may warrant some testing.

Possible later improvement could be moving the premultiplication from fragment
shader to CPU. Did not do this as it makes the code rather inconsistent of Kage
vs built-in shader usage.

f17d222a4b internal/atlas: resolve deferred every frame instead of every tick
Resolving defferred functions doesn't have to be done every tick. Rather,
this should be done every frame as this is related to rendering.
