    Graphical User Interfaces

Last time I wrote a little bit about
my current GUI research progress. There are some things that were misunderstood so I want to clarify
some fundamental design decisions and finally write up some current problems and their solutions.
First up I want to clarify a component is not another term for what is usually refered to as widget.
Instead wigets in this implementation are made out of n >= 1 components. Components themself are just
rectangles with attributes left, right, top, bottom, center_x, center_y, width and height some behavior flags
and an optional surface to draw into. For example a scroll regions is made up out of at least three

  
## fibers.c
#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <stdint.h>
#include <assert.h>
#include <string.h>
#define streq(a, b) (!strcmp((a), (b)))

#ifndef __USE_GNU
#define __USE_GNU

                Minimal Code Generation for STL-like Containers
              
          
    This is my little Christmas-break experiment trying to (among other things) reduce
the amount of generated code for containers.
THIS CODE WILL CONTAIN BUGS AND IS ONLY PRESENTED AS AN EXAMPLE.
The C++ STL is still an undesirable library for many reasons I have extolled in the
past. But it's also a good library. Demons lie in this here debate and I have no
interest in revisiting it right now.
The goals that I have achieved with this approach are:
