9d2178cf71 internal/shaderir: rename the built-in func to get a texel to __texelAt 2023-04-23 22:57:30 +09:00

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

00e45affe9 all: update OpenGL version from 2.1 to 3.2 
'texelFetch' requires OpenGLSL 1.30, which requires OpenGL 3.0+.
macOS might not support OpenGL 3.0 and 3.1, so adopt 3.2.
