Hi. What is the 'correct' way to determine the 'pixel' length of bitmap fonts rendered in OpenGL? I'm using 2D ortho and the wglUseFontBitmaps() function to build font character lists in Windows. If I want to measure the size of my resultant text (for centering, formatting etc), what is the correct way to do this?

Should I be using the Win32 GDI GetTextExtent() API function, or is there a means of determining the current 'cursor' position within OpenGL? The glRasterPos functions sets the output position, and as each character is rendered, the output position automatically advances.. so is there a glGetRasterPos perhaps that I could use?
