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:

	int wide, tall;
	GetHudSize( wide, tall );

	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.

Another way to handle diff. screen aspect ratios

I'm using one image per more screen aspect ratios.

	int screenWide = ScreenWidth();
	int screenTall = ScreenHeight();
	SetBounds(0, 0, screenWide, screenTall);

	int finalScopeSize = m_pScope->Height();
	int sizeDiff = (finalScopeSize - screenTall);

	finalScopeSize -= sizeDiff;

	float halfspacing = (screenWide - finalScopeSize) / 2;
	
	//Performing depth hack to prevent "clips" by world
	materials->DepthRange( 0.0f, 0.1f );

	m_pScope->DrawSelfCropped(halfspacing,0,0,0,m_pScope->Width(),m_pScope->Height(),finalScopeSize ,finalScopeSize,Color(1,1,1,1));

	//Fill with two black rects
	surface()->DrawSetColor(0,0,0,255);
	surface()->DrawFilledRect(0,0,halfspacing+1,screenTall);
	surface()->DrawFilledRect(finalScopeSize + halfspacing-1,0,screenWide,screenTall); 

	//Restore depth
	materials->DepthRange( 0.0f, 1.0f );
