27c530ec64 Expressions / introduce the match operator 
This operator allows mapping from input values to output values of different
kinds and handles variable arguments count.

e3f7d29bb2 Expressions / add utilities for using strings in GLSL & more type checking 
It is now possible to specify a type hint when parsing an expression, which
helps determine the output value type.

When no single output type can be inferred, an error is thrown.

For strings, every literal value will be replaced by a number and a map of
these associations will be kept in the parsing context, which is passed
recursively.

b8e8d30df0 Shader Builder / add utilities for checking an expression type 
Type checking is done either against a literal value (number, string...)
or against the operator in case of an expression.

Sometimes it is not possible to infer only one type, for example
the value 'transparent' could either be a color or a string. This
is covered by the fact that all operators expect exactly one type
for their arguments.

a0b271a812 Literal Style / add support for variables in the style 
These variables are accessed using the `var` operator, and are meant
to be mutated directly in the style object. When doing so,
the new value will always be used for the render.

This is intended to be used for modifying the style through external
parameters such as an input field, a slider, mouse position etc.
