🆕 _DISPLAY and _LIMIT and ❇ _NEWIMAGE

_DISPLAY and _LIMIT

Although BASIC Anywhere Machine ignores these statements, it does recognise them at runtime as valid QB64PE statements.  This is part of a longterm effort to get QB64PE programs running in BASIC Anywhere Machine (as much as possible) as is (without too much futzing about to get a program running.)

I'm thinking I might never get around to fully implementing these statements in BASIC Anywhere Machine.  I do, however, allow myself to change my mind ...

_NEWIMAGE

BASIC Anywhere Machine still only has this as a parameter for the SCREEN statement.

So partial compatibility with QB64PE.  In QB64PE, _NEWIMAGE is a function, with a return value that can provided to the SCREEN statement directly or via a variable that gets set to the return value of the function.

Today's new version of BASIC Anywhere Machine allows a little bit more compatibility with QB64PE.  BAM was allowing only screen modes in _NEWIMAGE's third parameter.  Now, the third parameter also allows one of the following values:  256 or 32.

Although this helps running QB64PE programs as-is in BAM, BAM converts both of the values 256 and 32 to 21 (screen mode 21), resulting in 32 bit (16 million colors).

I might eventually get around to setting up a 256 color mode in BAM if and when it becomes a hot request.

For now, I think this is good enough.
