• 2x2, 3x3, 4x4 reals matrix : 2, 3 or 4 groups separated by semi colons ( ; ) of 2, 3 or 4 floating point numbers separated by commas ( *,* ) or spaces ( ).
• rgb_colour : the RGB components of colour, expressed in floating point numbers between 0.0 and 1.0.

Description

The file is split into sections, defined as follows :

[section-type] "[section-name]"
{
    // Section description
}

Example:
