49582519c1 all: add a compiler directive kage:unit 
This change adds a new compiler directive 'kage:unit' to Kage. This
takes one of these two values: 'pixel' and 'texel'. The default value
is 'texel'.

With the pixel-unit mode, all the built-in functions treats pixels
instead of texels, and the texCoord argument of Fragment is in pixels.
This simplifies shader programs as programs no longer have the notion
of texels.

With the texel-unit mode, the behavior is the same as the current
behavior.

internal/graphicsdriver/opengl: fix state tracking of glBindTexture / glActiveTexture interaction (#2526) 
After switching texture units using glActiveTexture, a different texture may
be bound. For now, let's just force the active texture state variable to zero
so the next glBindTexture call isn't skipped.

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.
