ETX 2.10.6 Inconsistency with lcd.sizeText between telemetry and widget scripts.
Is there an existing issue for this problem?

What part of EdgeTX is the focus of this bug?
Companion
Current Behavior
The context is that I am writing a script for dual use - it can run either as a telemetry script (mono screens) or a widget (colour).
In the init() callback I have a call to lcd.sizeText() in order to cache the font height. Using the Companion simulator (TX16S), this works fine when runing as a widget. However in telemetry mode (TX12) it fails because lcd.sizeText is nil.
It would be useful to have lcd.sizeText() available in the init() function in telemetry scripts - this would allow screen layouts to be planned up front as well as being consistant with behaviour in widgets.
Expected Behavior
See above
Steps To Reproduce
- Create a simple telemetry script
- In the Init() function, attempt to call lcd.sizeText()

Anything else?
No response
lcd.sizeText() isn't supported at all on B&W screens regardless of where it is called. There are a limited set of functions available on B&W screens, I think you'll always have to check what you're running on and draw accordingly.
So where do we stand with this issue? lcd.sizeText() is (and has always been) a colorlcd only function, so this isn't a bug, but incorrect use of it on a non-colorlcd platform.
It would certainly be useful to have support for mono screens. Either way, the documentation should be more explicit, there's no mention of restrictions. https://luadoc.edgetx.org/part_iii_-_opentx_lua_api_reference/lcd-functions-less-than-greater-than-luadoc-begin-lcd/sizetext
