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.
