db34930ae8 internal/graphics: add built-in Kage functions
This change adds these Kage functions:

* imageDstOrigin
* imageDstSrc
* imageSrcNOrigin
* imageSrcNSrc

and deprecates these functions:

* imageDstRegionOnTexture
* imageSrcRegionOnTexture

Closes #1870

63df6168d9 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
```

.

Closes #2717

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.

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.

bc930ed0ec Revert "examples/shader: Rename ScreenSize -> ImageSize"
This reverts commit 3893f9cdbe.

Reason: The screen size and the image size can be different.
