Shader::set()
Sets a uniform of the shader: a value the shader reads but the
program decides, such as the time for an animation or a position on the
stage.
The name is the one the shader file declares, uniform float blocks;
is set with set("blocks", 20). There is a set for one or two
numbers or booleans, a Vector2, a
Color (as a vec3), and an array of
numbers, ncoords at a time, for an array uniform like
uniform vec3 lights[10];.
A uniform keeps its value until it is set again, so a value that changes is
set in run().
