Hey guys,
In my game, I have (0,0) at the bottom left, and slick-util was built for the orgin being the top left. I browsed the source and found that the drawing code for the font lies in line 247 of TrueTypeFont.java.
I changed it to:
1  
2  
3  
4  
5  
6  
7  
8

   /**
    * Draw a textured quad

    *            The left x position to draw to

    * @param drawX2

    *            The right source x position to draw from

    *            The bottom source y position to draw from
    */

   private void drawQuad(float drawX, float drawY, float drawX2, float drawY2,
         float srcX, float srcY, float srcX2, float srcY2) {
      float DrawWidth = drawX2 - drawX;
      float DrawHeight = drawY2 - drawY;
      float TextureSrcX = srcX / textureWidth;
      float TextureSrcY = srcY / textureHeight;
      float SrcWidth = srcX2 - srcX;
      float SrcHeight = srcY2 - srcY;
      float RenderWidth = (SrcWidth / textureWidth);
      float RenderHeight = (SrcHeight / textureHeight);
     
      GL.glTexCoord2f(TextureSrcX, TextureSrcY + RenderHeight);
      GL.glVertex2f(drawX, drawY);
     
      GL.glTexCoord2f(TextureSrcX + RenderHeight, TextureSrcY + RenderHeight);
      GL.glVertex2f(drawX + DrawWidth, drawY );
     
      GL.glTexCoord2f(TextureSrcX + RenderWidth, TextureSrcY);
      GL.glVertex2f(drawX + DrawWidth, drawY + DrawHeight);
     
      GL.glTexCoord2f(TextureSrcX, TextureSrcY);
      GL.glVertex2f(drawX, drawY + DrawHeight);
   }

to mirror the text upside down, based off the quad rendering code from another class in my game that actually works.
Also, I setup my projection view like this:
1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
12  
{//Init OpenGL Code
         //Setup an XNA-like clear color
         GL11.glClearColor(0.4f, 0.6f, 0.9f, 0f);
         // Map the internal OpenGL coordinate system to the entire screen
         GL11.glViewport(0, 0, gameWindow[0], gameWindow[1]);

         // Init OpenGL Window
         GL11.glMatrixMode(GL11.GL_PROJECTION);
         GL11.glLoadIdentity();
         GL11.glOrtho(0, gameWindow[0], 0, gameWindow[1], 1, -1);
         GL11.glMatrixMode(GL11.GL_MODELVIEW);
      }

This is what the code turns into.

Wow thanks! That was such a silly question  Undecided. But thanks for helping me! I was expecting the problem to be something deep within the dark chambers of LWJGL...
Thanks  Grin
