The Béziers are quadratic not cubic...

Béziers
It's hard to type the ́e so I will just call them Beziers from now.
New struct represents a cubic bezier, can be evaluated. The Objects struct contains a vector of beziers, and a vector of indices for each object.
If an ObjectType is BEZIER than the index can be used to look up the bezier control points. Control points are relative to the bounding rectangle;
so we can reuse the same curves (eg: For fonts).
Rendering happens on CPU only, sub divide and use Bresenham lines.
Bresenham lines are not quite optimal but I eventually gave up.
So we don't have a "line" type, but you can make one by creating a Bezier where x1,y1 == x0,y0
They look kind of wobbly.
Save/Load not tested. It might break. But it will have to be pretty heavily rewritten soon anyway.

Bugfixes for CPU rendering
Fix segfault caused by RectOutlineRenderer not properly checking bounds on pixel array.
Fix positioning of RectOutline sides in other locations when they were off the screen.
When you zoom in too far, an integer overflow will occur and the CPU rendered objects disappear.
This occured at widths of about 1e-7 (for our test pattern). Improved for now by int -> int64_t
Later need to replace everything except the actual array access with Real's I think. Then make Real's arbitrary precision. Done.
There is a slight size difference between CPU rendered and GPU rendered objects; not sure what the source of this is. Blame rounding.
GPU sometimes leaves off the corner pixels of the rectangles by the way.

Minor perf improvement on nVidia
nVidia's driver does not like you mapping a STATIC buffer, as they're
usually in parts of VRAM not directly accessible by the CPU. The driver
therefore has to migrate the buffer somewhere slower.
We initialize the object bounds buffer by mapping it and writing directly
into it. This is good where we're doing coordinate transform on the CPU:
we're changing it every frame and it can be a dynamic buffer, but we only
need to do it once if the GPU is doing coordinate transforms so we make it a
static buffer.
This change "fakes" mapping a STATIC buffer for the first time by allocating
some CPU-side memory, having the application write into that, and then initializing
the buffer with that. This removes a performance warning on nVidia when switching
to GPU-side coordinate transforms.

Tester for exploring the mapping of a float to a real
To visualise the mapping and how you get the trade off between precision and range.
Use low precision, custom, float representations.
Convert via memcpy(3) and copious bit shifting to a Real
Even though Real is actually also a float (default double) at the moment, it's good enough to treat as being an exact representation
when the custom float is 8 bits. Besides, gnuplot can only plot within double precision anyway.
I say "custom" because I have an explicit sign bit for the exponent, which itself is unsigned.
I *think* standard representations have the exponent be a signed int so the sign bit is implied.
Not sure why the mantissa is treated as being unsigned with an explicit sign bit but the exponent isn't?
HFPA says the exponent is between e_min and e_max which is a bit confusing. Is e_min != -e_max normally?
Will do some plots and experiment a bit after sleep.

Support doing coordinate transforms on the CPU
So because OpenGL (by default at least), does everything with

An interface for a FPU compiled from VHDL
I have tested with the FPU from https://github.com/jop-devel/jop
The way this works is really awful...
1. Make (or steal from jop) a VHDL FPU
2. Make (or steal from jop) a testbench that uses stdio to read operands and ops
- The jop one reads from a generated file, but it is trivial to change to "STD_INPUT" and remove all the assertion tests.
3. Compile testbench into an executable with ghdl
4. Call VFPU::Start which does the following:
- Create a socketpair(2)
- fork(2) and in the child dup(2) stdin/stdout to the socketpair
- Redirect stderr to /dev/null because the testbench generates 10^3 warning messages
- in the child, exec(3) the testbench FPU
5. Call VFPU::Exec passing the desired operands and opcodes
- The operands and opcodes are written as hex strings over the socketpair
- The child executing the FPU program does its thing
- The result is read back as a hex string
6. When finished, call VFPU::Halt to kill(2) the FPU
I tried to get ghdl and gcc/g++ to make a static library to call ghdl_main instead
of exec'ing things. But that didn't work. The fork and socketpair would have still been
required for that approach anyway.
TODO:
- Make the interface (not the FPU) deal with arbitrary size registers
- Wrap a Real type around it so we can #define REAL_SIMULATED_FPU
I haven't put any of the VHDL in the git repo for obvious reasons.
If I actually start messing with it, it will probably get a seperate repo.
This may end up being a complete waste of time?
Although potentially being able to run an arbitrary FPU albeit in a horrible manner does seem cool.
