e35cfd4971 get rid of the redundant 'f' suffix of several funtions in floats module (breaking change!)
Unfortunately a few routines (minf, maxf, clampf) remain unchanged, because removing the 'f' would make them clash with a builtin function.

floats.rndf -> floats.rnd
floats.parse_f -> floats.parse
floats.rndseedf -> floats.rndseed
floats.print_f -> floats.print
floats.str_f -> floats.tostr

corrected to upper case: cx16 kernal calls CLOSE_ALL, LKUPLA, LKUPSA, JSRFAR, PRIMM, MACPTR.

ee81da14d6 cx16: removed monochrome modes from gfx2 (use monogfx instead). New screen mode numbering!
programs will now be a lot smaller than before if they use gfx2 (or monogfx if they were only using monochrome drawing)
monogfx also fixes some drawing errors with small horizontal lines, and stippled vertical lines.

a289b32053 Revert "added -verafxmul compiler option to use vera fx multiplication routine on cx16"
This reverts commit 690782bf.
It was too risky, using vera (especially fx) transparently in multiple places especially perhaps in IRQ handlers will create havoc unless much intricate care is taken to save/restore the vera state. Better to do vera fx explicitly where the programmer has full control.
