Thank you for decades of dedication to this incredible application (and thanks again especially for the Genlock-enhancements).

"brdntran" can be used to force enable BPLCON2 BRDNTRAN bit, "brdrblnk" to force enable BPLCON2 BRDRBLNK bit. Separated by comma. (for example "genlock_effects=3,15,p7")
- Genlock sprite color selection bug fix.
- Genlock ECS Denise BPLCON2 BRDNTRAN emulation fixed. Not real HW tested but I think it is supposed to make border look normal even if color 0 is genlock transparent.
- Genlock ZCLKEN BPLCON3 bit emulated, if set, genlock transparency video out pin (PIXELSW) starts outputting 14MHz pixel clock. Emulation creates alternating hires pixel size toggling transparency if enabled and genlock is configured. (Which probably is what happens in real world too when genlock is connected. Originally it probably was supposed to be pixel sync signal for external video devices)
- Added Output panel optional 256 color palette indexed png screenshot support. If screenshot has more than 256 unique colors, 24-bit png is created like previously. It also tries to keep original palette order: first screenshot's unique colors are collected, then custom color register values are collected (values at the end of previous field), screenshot colors are matched with custom colors, if match found, color is marked as allocated. Then all remaining colors (copper color changes, EHB, HAM, on screen leds, blanking black etc..) are added to palette. If total is more than 256, 24-bit png is created. 256 color mode also tries to preserve first 32 color palette entries. (Preserved = color is not overwritten by another color even if color is not used in screenshot)
- Optional IFF screenshot support (-screenshotiff or screenshot_mode=2 registry/ini). IFF mode does not attempt to preserve first 32 color palette entries to keep image depth as small as possible. IFF is not (yet) compressed
