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.

Closes #1431

do not require installing file2byteslice to update go generate'd files. (#2221) 
The tool is already referenced in go.mod, so it is trivial to just go run it -
that way, go generate can use it without the user explicitly installing it first.

70acb9c1f6 shader: Rename shader bultin functions 
Renamed image0TextureSize to imageSrcTextureSize, and removed the
other texture-size functions.

As texture-coordinates are always in image0's texture texels,
calculations with texels are always done with image0's texture texels.
Then, other texture-size functions are useless. To avoid confusion,
let's remove the functions and leave the necessary funciton.
