       dtk_load_image - Load an image file as a texture


       #include <drawtk.h>

       dtk_htex dtk_load_image(const char *filename, unsigned int mxlvl);


       This  function  load  the  image  file specified by filename argument. It will creates the
       mipmaps until level mxlvl. Upon creation,  the  texture  will  then  been  tracked  by  an
       internal  texture  manager  so  that  the  next call using the same filename argument will
       return the same texture handle, thus sparing the resources of the system.

       There is no need for a valid window to create successfully a texture,  i.e.   creation  of
       textures  are  completely  decoupled from the creation of others resources and can even be
       created in one thread to be used in another one.

       Mipmaps are version of the same image at lower resolution (every power of two). Mipmap  at
       level 0 is the original image. Given the size of the texture displayed in the framebuffer,
       the closest mipmaps are used to interpolate the value of displayed pixels. Do  a  research
       on internet for further details about mipmaps.


       In  case  of  success, the function returns the handle to the created texture.  In case of
       failure, NULL is returned.


       dtk_load_image() is thread-safe.
