* imageDstOrigin
* imageDstSrc
* imageSrcNOrigin
* imageSrcNSrc
and deprecates these functions:
* imageDstRegionOnTexture
* imageSrcRegionOnTexture

internal/shader: use plural forms for Kage compiler directives
...
This change renames
```
//kage:unit texel
//kage:unit pixel
```
to
```
//kage:unit texels
//kage:unit pixels
```
.

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.

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.
