Answer 1

nowadays, that is the answer. No need any code hacks
Probably you use themes, if not, you should use that technology:

• Project Options > Application> Appearance

• Check on one of them as Default Style)
  
  than :
  

• Tools > Bitmap Style Designer > Open Style
  

• Navigate your vsf style file
  (probably right here "C:\Users\Public\Documents\Embarcadero\Studio[VERSION]\Styles

• Now In Bitmap Style Designer.. navigate to:
  Objects > Tabs > Frame > Bitmap

• Click [...] three dot button of Bitmap In Inspector
  
• Zoom to 800%
• Pan/Scroll and Focus on to bitmap rectangle range.
• Right Mouse Click to change Upper-Left, Left Mouse Click to change Lower-Right region.
  (so select inner rectangle to eliminate border bitmap now you have borderless page controls)
