Graphics viewport and coordinate mapping: - VIEW [[SCREEN] (x1,y1)-(x2,y2) [,[fill][,border]]] with clipping - WINDOW [[SCREEN] (x1,y1)-(x2,y2)] with Cartesian/screen modes - PALETTE [attribute, color] with CGA 16-color remapping - PMAP(coord, func) for logical/physical coordinate conversion - All graphics statements (PSET, LINE, CIRCLE, PAINT, GET/PUT) respect viewport clipping and WINDOW coordinate mapping MBF (Microsoft Binary Format) float support: - CVS/CVD now interpret bytes as MBF format (compatible with real GW-BASIC) - MKS$/MKD$ now produce MBF-encoded bytes - Fixed shift errors in MBF↔IEEE conversion routines (single: 1→0, double: 4→3) - Random-access file I/O now byte-compatible with original GWBASIC.EXE 66 tests (2 new), 61 compat matches (up from 58).
