v0.40.0

Changes since v0.40.0_preview_3

• Colour Model

• phase adjustments can now be applied to the standard Stella palette
• this more closely matches modern expectation while also providing the flexibility to adjust the phase if required
• removed 'Legacy Colour Model' option
  • preview releases of v0.40.0 allowed A/B testing of the 'legacy model' and a purely mathematical model
  • explanation of the current model in the blog https://jetsetilly.github.io/Gopher2600-Blog/posts/improving-the-ntsc-colour-model/

• Improved DWARF decoding

• binaries compiled with no optimisation (or -O0) now show variable information in the debugger
  • absence of .debug_loc was incorrectly considered to mean no location information was available
• framebase uses the yield address and not the current PC address
  • very often this doesn't matter but incorrect use of the ARM pipeline caused variables to be missing unexpectedly
• function building uses specification attribute if appropriate
  • this attribute seems to be used in object-oriented style C++ programs, and is probably a feature of other OO languages

• ELF

• added vcsJmpToRam3(), vcsPokeRomByte() and vcsSetNextAddress() strongarm functions
• improved performance when accessing executable memory
• ELF can now annotate coprocessor disassemblies

• Bug Fixes

• race error between SDL audio and playscreen overlay (the FPS overlay)
