[Camera] Allow setting of capture resolution

[DelphiWorlds]

As per title, add ability to set resolution of captured images

[limadavi]

To save the image with a fixed resolution I am doing the following:
ImageViewer.Bitmap.LoadFromStream (FCameraView.ImageStream);
PHOTO: = ImageViewer.Bitmap;
PHOTO.Resize (1024,1024);
This worked for my app.

I take the captured image, add it in an ImageView to facilitate the user's visualization, but to save it I add the image in a TBitmap type variable, then I configure Resize to the size I need and save the image in the app's database.
