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.

609a3c4e22 ebiten: Bug fix: Fix the texel calculation
In shaders, texCoord is always in texture0's texels. Convert them
at imageNTextureAt functions correctly.

4021c24534 shader: Separate uniform variables and texture variabls
Textures cannot be treated as a regular variable, then they should
be treated differently from other uniform variables.

Add a new function texture0At replacing texture2D.
