* Docs: Overhaul the default keys list
* Second phase of documenting default inputs better, also change Score to Take Score in Mahjong inputs
* Phase two of default keys docs adjustment.
* Updated to new stream callback
* All calculations are now doing in floating point
* External input is now done via an input stream
* First attempt at implementing a proper filter -- needs some major
work; checking in current state to get some assistance
Components may have multiple bounds and/or color child elements with
state attributes, allowing for piecewise linear position/size/colour
animation.
Components may have a statemask attribute, allowing for things like
using external images to draw a multi-segment LED/VFD display without
requiring dozens of outputs for the individual lines or thousands of
images for all possible states. (Texture caching still never releases
anything, so MAME can still exceed the maximum number of textures, but
that’s a separate issue.)
Image components with alpha now blend over previously drawn components.
Layouts have been changed to use yes/no for inputraw to match what's
used for flipx/flipy. External layouts with 1/0 will still work, but
complay.py will complain.
* animalc: Pile kludge upon kludge for poorly understood video timing register
* gocowboy, itazuram: Increase frequency of one timer interrupt (and hopper timing in gocowboy)
* kc82, kp69: Modernize state_add syntax
Significant internal changes to sound streams:
Abstracted buffers of sound data into an internal stream_buffer class, with helper classes read_stream_view and write_stream_view which offer readable/writable "views" into the buffers
Internal sound calculations are all done using stream_buffer::sample_t, which is a 32-bit float; existing callbacks are supported through an adapter that converts to/from signed 32-bit integers
Improved behavior of dynamic stream sample rate changes to resample a short runway of data to preserve continuity across transitions
Created a new stream update callback which passes a std::vector of read_stream_views for inputs, and a std::vector of write_stream_views for outputs
Updated core mixer and speaker devices to the new stream update callback
Updated the following sound cores to the new stream update callback: ay8910, dac, k054539, msm5205, namco, netlist, okim6295, pokey, samples, sn76496, sp0250, tms5220, tms57002, upd7759, vgm_visualizer, volt_reg
Changed existing stream update callback to make inputs explicitly const and the output pointers const as well, since they are re-used across calls; fixed several engines that violated this rule
Sound_manager::stream_alloc can no longer automatically connect to a device's sound_stream_update callback; instead, the stream_alloc() on the sound_device_interface should be called; updated many violators of this rule
Streams can be created with SAMPLE_RATE_OUTPUT_ADAPTIVE, which dynamically tracks the sample rate of its first downstream output, or with SAMPLE_RATE_INPUT_ADAPTIVE, which tracks the sample rate of its first input
Changed resampling to be a separate sound_stream that is invoked as needed, opening the path for selectable resampling implementations
Added a flags parameter to the new stream allocation method that allows you to specify a that input streams should not be resampled
Exposed stream_input and stream_output classes directly, simplifying access to user gains and stream names
Added a simple dynamic compressor to sound_manager to provide nicer results when overdriven sound happens; compression does not affect speaker_report results
Improved verbose speaker_report to print a graph of peaks over time
More aggressive debugging enabled for now even in release builds (should be disabled prior to next release) via SOUND_DEBUG define in sound.h; report any assertions for fixing
