Version v20-20240421-1218:

First release of v2 version of VDCSE
Completely rebuild using the Oscar64 compiler (previously CC65)
Added support for multiple VDC text screen modes, including 80x50 (ideal for C64 PETSCII art aspect ratio). NB: Needs a C128 with 64KB VDC RAM to have still also room for swap VDC memory.
Added import and export functions: Import of both raw screen data in PRG files, or BBS Petscii code sequences in SEQ format export to SEQ format. SEQ format can be a.o. used to import from and export to other PETSCII editors like Petmate 9.
Import functions include a VIC to VDC colour converter. Which is obviously a comprimise as VDC has only one color as alternative for the VIC pairs Orange/Brown (both convert to VDC Dark Yellow) and Light Grey/Medium Grey (both convert to VDC Light Grey), and the other colours have different hues on VDC than on VIC (for example light red from a pink like hue on VIC to red on VDC)
Import can be done to any given coordinate in the existing project, canvas is automatically enlarged if needed to make it fit.
VDCSE2PRG program generator now supports all screensizes that fit in memory and supports the different screenmodes. Features scrolling for sizes bigger than the screensize: smooth scrolling on 64 KB VDC RAM equiped machine and per char vertical scroll (no horizontal scroll) with 16 KB VDC. Project files can now be selected using a filebrowser.
Many smaller refinements and bugfixes
