Bugfix display of disabled screen.
It is possible to select a screen as default which is in parallel disabled in the selection view. To avoid this the enable / disable state is not also checked when entering dive mode. The check function was depending on an ACTION. The functionality has been changed to allow the function call without ACTION.
Changed setting of compass circle position from constant position to variable
This was needed to reuse the same function in several views with different compass position
Added new views Navigation and Depth data
Both views were basically already available but the idea behind the layout is to combine all information needed for navigation dives (compass + timer) in one view. The classic maxdepth view just showed the maxdepth with a black box on the right side. this box is now used for display of average depth (shown in classic view Stopwatch)
Minor changes in compass paint function to improve code readability
Use same Y offset for all views
While switching across the views some number were shown ~20 pixel higher than others. This was caused by the usage of the line selection which works for some fonts but not for all => set linenumber to 0 for all views

# OSTC4 Code Modules # ## Main CPU - aka CPU1-Discovery ## For historical reasons, the firmware of the main CPU was divided in three parts. It helps development, allow smalled upgrades, and improve security as a bad manipulation won't kill the bootloader, responsible fot the next firmware upgrade. ### Bootloader ## The code responsible to upload new firmwares for both CPU. ### Font Pack ### This module does not contains any code. Just font data and images. ### Firmware code ### The main OSTC4 firmware. The more important modules are: - Buehlmann decompression algorithm. - VPM decompression algorithm. - The simulator and dive planner. - Logbook display (surface and dive mode). - All user interface code, during dive or surface mode (`t*.c` files). - Graphics (gfx) engine. - Plus interface to the other CPU, the management of the _LCD_ screen, and the optional _Bonex_ scooter interface (No longer supported) ## Small CPU - aka CPU2-RTE ## The _Real Time_ CPU handle everything that requires precise timming to function perperly. The most important modules are: - Real time computation of gas exchanges during dive (aka the _LifeData_ structure). - Analog to digital conversion for the ... ambient light sensor. - I2C bus interface to the pressure sensor, the magnetic compass and the battery gauge. - SPI bus interface to the buttons and to the other CPU. - Serial interface to the _RS232-over-Wireless_ connection.
