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

a1dd7b39a3 graphics: Remove roundTexel function
Actually, at least 704d4cf464,
examples/moire doesn't work well without roundTexel on MacBook Pro.
However, now other parts are fixed (e.g. highp is used), it looks
like roundTexel is no longer needed.

0b7ba8e573 Do GeoM projection on CPU (#477)
Handling GeoM projection on CPU may seem like a weird choice, given
how fast GPU is, but it pays off:

* You only have to do a very small subset of the actual matrix
  multiply.
* You don't have to construct a matrix in the vertex shader.
* Six fewer float32 values per vertex.
* You do still have to do the matrix computation for each vertex,
  though.
