Irmen de Jong	e1835b5775	removed dysfunctional c128.graphics library module	2023-10-05 21:03:47 +02:00
Irmen de Jong	433832b329	gfx2.clear_screen and monogfx.clear_screen() now have color parameter to clear the screen with ... this is much faster than filling a rectangle of the full screen size with a color.	2023-10-05 21:00:39 +02:00
Irmen de Jong	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.	2023-10-05 02:12:46 +02:00
Irmen de Jong	6395d1908e	cx16: added monogfx library module, replaces gfx2 for monochrome screenmodes.	2023-10-04 22:32:13 +02:00

Irmen de Jong	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.	2023-10-02 21:08:52 +02:00
