ea04e2a9de ebiten: remove returning error from ReadPixels 
- As ReadPixels should often be used at Draw, error handling would be hard.
- Make the API consistent with ReplacePixels.

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.

54b4e87506 internal/restorable: bug fix: ReplacePixels on a sub-image might panic on Android 
If regions by ReplacePixel are overlapped, this can panics. This can
happen only on Android, where a context lost can happen.

Thus, a sub-image cannot call a direct ReplacePixels. internal/buffer
has to care this.

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.
