===TEXTURES===

Stupid man pages (of cygwin & [[Debian]]  200404) , dont believe liers :
  # man glTexImage2D
  ... 2n+2(border) for some integer  n.  All  implementations ...

I Suppose the 'n' in 2n+2 was noted as an exposant, and the ntroff filter ommited the '^' in 2^n+2


http://sourceforge.net/tracker/index.php?func=detail&atid=100003&aid=949337&group_id=3


  <RzR> sous opengl on peut charger des textures de tailles 2n+2 x 2m+2 ? je croyais que c t 2^n x 2^m
  <rem`> RzR: si t'as l'extension pr avoir des textures rectangulaires :)
  <RzR> ha c bien ce ke je pensais
  <rem`> GL_EXT_texture_rectangle, GL_NV_texture_rectangle
  <RzR> sinon faut faire du padding a la main


  makeCheckImage();
  GLuint* gltexturename_ = new GLuint[[1]];
  glGenTextures(1, gltexturename_ );

  glTexImage2D(GL_TEXTURE_2D, 0, 3, 64, 64, 0 , 0, GL_UNSIGNED_BYTE,
               p_texture_default_ );

  assert( glIsTexture( *gltexturename_ )  ); //crash why ?

==== TRANSPARENCY ====

Do not use Accum buffer :
  * render to texture  et apres tu fades entre tes textures
  * r l'alpha de ton mesh au pire tu rends dans une grosse texture
  *vi ou tu bouge l'alpha du mesh si c par mesh ouai meme en 1024x1024 ca passe

  glBlendFunc(GL_SRC_ALPHA,GL_ONE);
  glColor4f(1.0f, 1.0f, 1.0f, 0.5);

  glTexEnvi(GL_TEXTURE_ENV,GL_TEXTURE_ENV_MODE,GL_BLEND);
  glColor4d(1,1,1, (GLdouble) a);
  glTexParameterf( GL_TEXTURE_2D, GL_TEXTURE_PRIORITY, (GLfloat) a );
