problems:
it is not correctly displayed (vertice and what happend to the texture?)
todo:
improve the import, remove unused garbage,
add move and zoom function

added keyboard support,
reset rotation with space

Features:
- performance improvement,
- code improvement,
- move the model to the center,
- scale everything to 1,
- do not open a default file for release build
Bugs:
- cloth is not displayed correctly,
- turning in the wrong x direction when model is turned 180° in y direction,
- consular class corvette is not displayed,
- rep_weap_LJ-50 is not displayed correctly

cloth not displayed completely,
corvette is not displayed why?

clean up variables,
use delete[]

use else if

reading bbox for each geom,
added some TODO
use the bbox information

garbage is not from the texture or object changes

don't copy the data, give a pointer,
there is some data left, need to find out if it's from these changes

Features:
- fixed texture problem
- fixed multi polygon problem
Bugs:
- cloth not working correctly,
- seams that bones as parent do not work

added new multipoly for testing

Features:
- reset view before loading new mesh
- reset view when pressing space
- clustered msh can be displayed
- shadow mesh, nulls, bones, hidden things are no longer displayed
- now mulitpolygons can be displayed
- fasten and improved code
Bugs:
- cluster mixed up textures,
- at most mesh only every 2nd triangle is displayed,
- triangulation is not very good (DarthDUCK's Proton charge)

tested multipoly, there are some problems, look at the README.md,

now need to test it

removed the old unused code

At the moment there is a problem with the UV using the new method

new implementation of segm read strp to not only read triangles,
needs to be included in the buffer fill function/draw function

reset view when pressing space

Features:
- drag and drop

next step: calculate best first view position

need to clean up before loading the next mesh
