30cc36b1ba ebiten: add FinalScreenDrawer 
FinalScreenDrawer is an interface for a custom screen rendering. If a
game implements FinalScreenDrawer and is passed to RunGame, its
DrawFinalScreen is called after Draw.

Also this adds `-crt` option to examples/flappy.

d4e7676daa ebiten: do not use mipmaps at DrawTrianglesShader 
This change stops using mipmaps at DrawTrianglesShader. Though this
is a brekaing change, the shader APIs are experimental in v2.4, and
the extent of the impact should be pretty small as DrawTrianglesShader
is a rarely-used low-level API.

For DrawRectShader, mipmaps were not used even before this change.

f293a03ab6 internal/mipmap: reland: do not consider filter to determine mipmap level 
This is a reland of 42833614fb.

Now the filter argument is not used (a4e9a05b14),
the filter value can be the nearest filter even though the shader is
for the linear filter.

As long as `canSkipMipmap` is set correctly, we don't have to consider
the parameter `filter`. We should ignore it.

a4e9a05b14 ebiten: reland: use Kage shaders instead of built-in shaders for a color matrix 
This replaces the built-in shaders with Kage shadres. This is a
refactoring and doesn't degrade performance:

```
go test -bench=^BenchmarkColorMScale$ -run=^$ . -count=5
```

```
name           old time/op  new time/op  delta
ColorMScale-8   978ns ±15%  1184ns ±46%   ~     (p=0.413 n=4+5)
```

A follow-up change to remove the built-in shaders is needed.

bac34a4474 ebiten: add NewImageWithOptions and NewImageOptions 
This change adds NewImageWithOptions, that creates a new image with
the given options.

NewImageWithOptions takes image.Rectangle instead of a width and a
height, then a user can create an image with an arbitrary bounds.
A left-upper position can be a negative number.

NewImageWithOptions can create an unmanged image, that is no longer
on an automatic internal texture atlas. A user can have finer controls
over the image.

This change also adds tests for this function.

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.
