all references to opengl are now made through the renderer interface.
which renderer is to be used is controlled by buildtags
now requires minimum go version of 1.21
CRT preferences and CRT preview in debugger TV window are disabled for
OpenGL2.1
go-wav, statsview and memviz all indirectly used gopkg.in/yaml.v3 which
I do not want to depend upon
WAV functionality is no longer available for wav writing or reading
(supercharger tapes). will try to reintroduce functionality in the
future
added some icons to debugging screen. more will be added
embedded fontawesome free webfonts and a minimal Gopher2600-Icons font
that contains the controller images
bumped minimal go version to 1.16 to support the new embed directive
updated drawListSequence to support frame alignment
updated imgui-go to support new Style.Color() function
changed colors of some GUI elements
corrected labelling of SWACHA to SWCHA, removed SWBCNT and
reorderd widgets
unified/normalised static area structure and presentation
better tab bars for static area window
corrected cropped cursor drawing for pixel position on the VBLANK
boundary
TV specification changeable at command line and via GUI's debug screen
window
abstracted resizing mechanism opening the possiblity
for more sophisticated analysis
digest/video handles TV specification changes
bumped imgui-go version to 2.4.1
playmode now uses the sdlimgui playmode, rather than a separate pacakge.
this removes a lot of duplicate code but it should also make it easier
to add support to flip between debugger and playmode on the fly.
bumped imgui-go version to 2.40
removed analysis code. too many code paths rendered the method
unworkable. for example, eg. JMP (indirect) where indirect address is in
ram.
Clarified how the Bank field in the disassembly.Entry should be used.
win_disasm makes sure that the current PC entry has been blessed. making
sure it will be seen in the disassembly window (also a note in debugger
inputloop about the fact that blessing should really take place there,
except for race condition issues. TODO note added)
added status line and options to win_disasm. status line shows when
execution from VCS RAM is taking place. options for highlighting addresses
common between all banks and non-decoded addresses
requires some work, at the moment the limiter works whenever a new frame
is triggered, this is fine for high frame rate but it breaks down at
very low frame rates
updated DrawList function to use new PackedColor type
