Much of the time we use the term "analogue gain" where we really mean the combined analogue and digital gain (because the digital gain will make up whatever the analogue gain can't deliver). This commit replaces the use of "analogue gain" by just "gain" in places where we really mean the combined gain. There are a couple of principle areas: 1. Where we previously talked about the "fixedAnalaogueGain" (including setting it "manually") this is now just the "fixedGain" (because it always encompassed both analogue and digital gain). Along with this, the setfixedExposureTime/Gain functions no longer update the output status directly. Applications should wait in the usual way for AGC/AEC changes to take effect, and this "shortcut" actually doesn't fit well with the gain being the combined gain. 2. The divideUpExposure method is adjusted to be clearer that it's setting the combined gain, and it's prepare() that will discover later what the analogue gain actually delivered.

libcamera for the Raspberry Pi
Raspberry Pi provides a fully featured pipeline handler and control algorithms (IPAs, or "Image Processing Algorithms") to work with libcamera. Support is included for all existing Raspberry Pi camera modules.
libcamera for the Raspberry Pi allows users to:
- Use their existing Raspberry Pi cameras.
- Change the tuning of the image processing for their Raspberry Pi cameras.
- Alter or amend the control algorithms (such as AGC/AEC, AWB or any others) that control the sensor and ISP.
- Implement their own custom control algorithms.
- Supply new tunings and/or algorithms for completely new sensors.
How to install and run libcamera on the Raspberry Pi
Please follow the instructions here.
