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.

ba8ea50d57 ebiten: Follow image.RGBA64Image's aim
image.RGBA64Image aims to get 64bit color values efficiently to avoid
allocating an original color value and converting it to colorRGBA64.
Thus, we should avoid allocating color.RGBA for RGBA64At.

26b9fa20c1 internal/graphics: Bug fix: Race condition at QuadVertices
QuadVertices or verticesBackend.slice reused its backend slice.
This caused a race condition. QuadVertices can be accessed from
multiple goroutines, and resetting the head and copying the data
at internal/graphicscommand might not be synced.

This change fixes this issue by basically reverting
9cb631e30f.

5a62587df5 ebiten: Bug fix: The vertex backend was not flushed when the screen is shrunk
The last parameter of QuadVertices represents whether we can flush
the backend vertices (on Wasm). The problem was that this was
unexpectedly false even though the image is the screen, when the
screen rendering is done with FilterLinear instead of FilterScreen.

c7330883ef restorable: Remove Fill and make (*ebiten.Image).Fill available for sub-images
Now a scissor (a clipping region) can be specified, we don't have to
worry about the rendering results out of the specified region.
Replace the implmenetation of the Fill with just a DrawTriangles with
an empty white image.

As a side effect, SubImage is avilable for Fill.
