Different way to handle Screen Ratios

I got a different (and maybe better) way to handle the different screen ratios. This works by just adding black bars (assumed that your scope-image is black) on the Top and Bottom or Right and Left. The Code for this is pretty simple, just some mathematics are involved:

	float fAspectRatio = (float)wide / (float)tall;
	float fAspectRatioCRT = 4.0f / 3.0f;

	if( fAspectRatio == (4.0f / 3.0f) ) //Normal CRT (4:3)
	{
		vgui::surface()->DrawTexturedRect( 0, 0, wide, tall );
	}
	else if( fAspectRatio < 1.33f ) //LCD 5:4, draw at full width with bars on top & bottom
	{
		int iImageHeightHalf = (int)(((float)wide / fAspectRatioCRT) / 2 );
		vgui::surface()->DrawTexturedRect( 0, tall/2 - iImageHeightHalf, wide, tall/2 + iImageHeightHalf );
		vgui::surface()->DrawSetColor( 0, 0, 0, 255 );
		vgui::surface()->DrawFilledRect( 0, 0, wide, tall/2-iImageHeightHalf ); //Top Bar
		vgui::surface()->DrawFilledRect( 0, tall/2+iImageHeightHalf, wide, tall ); //Bottom Bar
	}
	else //LCD 16:9 or 16:10, draw at full heigth with bars left & right
	{
		int iImageWidthHalf = (int)(((float)tall * fAspectRatioCRT) / 2);
		vgui::surface()->DrawTexturedRect( wide/2 - iImageWidthHalf, 0, wide/2 + iImageWidthHalf, tall );
		vgui::surface()->DrawSetColor(0,0,0,255);
		vgui::surface()->DrawFilledRect( 0, 0, wide/2 - iImageWidthHalf, tall );//Left rectangle
		vgui::surface()->DrawFilledRect( wide/2 + iImageWidthHalf, 0, wide, tall );//Right rectangle
	}

This works good for me, and I think its less work to implement.
