-- Driver: prove the banded sky still paints from the ramp texture.

|
|
-- The bands used to reach the shader as `uniform vec3 bands[8]`, which on
|
|
-- Android delivered only its first few slots and painted the rest of the sky
|
|
-- black (see lib/Sky.lua, rampFor). They are a texture now. This checks the
|
|
-- three things that swap could have broken, on the machine it CAN be checked
|
|
-- on: that the shader still compiles, that the ramp is built and is one texel
|
|
-- per band, and that what lands on screen is still a gradient that pales
|
|
-- downward rather than a flat plate or a black one.
