79bd1341eb NES: Double-buffered deferred LCD ISR support for less graphics glitches, at expense of more RAM usage. (#751) 
- Define new constant .MAX_DEFERRED_ISR_CALLS as .MAX_LCD_ISR_CALLS+1

- Refactor vsync function for double-buffering, and have it flip the read index at completion

- Refactor .do_lcd_ppu_reg_writes, and rename to .do_hblank_writes

- Remove scroll glitch mitigation in .do_hblank_writes, as no longer needed

- Redefine __lcd_isr_ arrays sizes as 2*.MAX_DEFERRED_ISR_CALLS

- remove redundant ZP variable __crt0_disableNMI, as no longer needed

- TAB -> space conversion

- Add implementation for set_interrupts in lcd.s, replacing JMP instruction with RTS when disabled

- Enable NES target in examples/cross-platform/irq and replace delay(1000) call with 60 vsyncs

- Update examples/cross-platform/scroller and examples/cross-platform/irq to use set_interrupts

- Update documentation to describe use-cases and limitations of TIM handler

4512564d78 png2hicolorgb: merge in upstream changes 
- Added --palendbit : Sets unused bit .15 = 1 for last u16 entry in palette data indicating end, instead of having to count or check the current scanline. 
- Added --addendcolor=N: Appends 32 x color N (in hex BGR555, 64 extra bytes total) in the palette data to clear the background and avoid artifacts on source images that are shorter than the screen height. 
- Added --precompiled mode
