Summary: Monsters and goodies partly in floor.

Initial Comment:
Odd problem with matrox G450 in GL mode:


p_glTranslatef(sprite->x,sprite->y,sprite->z);

I hacked a fix but am not sure WHAT I did.
p_glTranslatef(sprite->x,(sprite->y+0.04),sprite->z);

Reference:

static void gld_DrawSprite(GLSprite *sprite)
{
  gld_BindPatch(sprite->gltexture,sprite->cm);
  p_glMatrixMode(GL_MODELVIEW);
	p_glPushMatrix();
	p_glTranslatef(sprite->x,sprite->y,sprite->z);
	p_glRotatef(inv_yaw,0.0f,1.0f,0.0f);
	if(sprite->shadow)
  {
    p_glBlendFunc(GL_DST_COLOR, 
GL_ONE_MINUS_SRC_ALPHA);
    //p_glColor4f(0.2f,0.2f,0.2f,(float)
tran_filter_pct/100.0f);
    p_glAlphaFunc(GL_GEQUAL,0.1f);
    p_glColor4f(0.2f,0.2f,0.2f,0.33f);
  }
  else

I will make it configureable.

When I set the number above the 'problem' was not 
noticeable to me unless I crafted a special level that let 
me look at their smelly feet. ;-)

If not too much trouble you could add an up/down offset to 
a config somewhere in case .04 was not compatible with a 
different vid card than a Matrox G450.

Yes I see this too. I'm assuming it's because the sprites 
in Doom overlap the floor slightly in software mode (i.e. 
the sprites are taller than the monster, to allow the 
monsters' feet to stick forward on the floor tiles, kindof 
- they'd look like they were on tiptoe otherwise).

This is a visual effect that may be tricky to duplicate in 
GL mode, perhaps if we slanted the sprites (or bottom 1/4 
of the sprites, or something)?
