Most importantly, the separate command line options for switching on the legacy buffer handling have been removed.
There's really no need for them anymore, because unlike in earlier versions many of the implementation differences no longer exist - with the exception of where the light and vertex buffer contents are generated.
For testing this, -glversion 3 is sufficient.
This eliminates 3 of the 5 remaining occurences of FQuadDrawer and gets a large section of code out of the GL backend into the common hardware rendering code.

This necessitated removing the reallocator because that cannot be done in a multithreaded context in OpenGL. The buffer should be large enough anyway, it it all gets used, slowdowns would be unavoidable.
There was also some simplification of the buffer alignment math for uniform buffers
The instruction one free instruction byte so it's now using that to extend its argument's register range to 65535.
For param this is needed because it passes strings by reference and creating an implicit temporary copy for string constants does not work here.
This feature causes several issues with NSOpenGLView:
* Mouse event coordinates are wrong in non-retina mode on HiDPI screen
* In retina mode only 1/4 of picture is visible and its scaling is incorrect
* Some sort of filtering is applied to frontbuffer picture
* Noticeable increase in CPU load because of that filtering
Linking with macOS 10.14 SDK leads to all these issues regardless of .plist option presence and its value
Added full-panning stereo, improvement of channel management, and many other things.
Also, I have implemented an ability to use custom WOPL (for libADLMIDI) and WOPN (for libOPNMIDI) banks from the same path as "soundfonts", but also, in the same environment, the "fm_banks" folder was added for WOPL/WOPN storing purposes.
To toggle usage of embedded or custom bank, I have added togglable booleans. When bank fails to be loaded, the default embedded bank is getting to be used as fallback.
ADLMIDI 1.4.0 2018-10-01
* Implemented a full support for Portamento! (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
* Added support for SysEx event handling! (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
* Added support for GS way of custom drum channels (through SysEx events)
* Ignore some NRPN events and lsb bank number when using GS standard (after catching of GS Reset SysEx call)
* Added support for CC66-Sostenuto controller (Pedal hold of currently-pressed notes only while CC64 holds also all next notes)
* Added support for CC67-SoftPedal controller (SoftPedal lowers the volume of notes played)
* Fixed correctness of CMF files playing
* Fixed unnecessary overuse of chip channels by blank notes
* Added API to disable specific MIDI tracks or play one of MIDI tracks solo
* Added support for more complex loop (loopStart=XX, loopEnd=0). Where XX - count of loops, or 0 - infinite. Nested loops are supported without of any limits.
* Added working implementation of TMB's velocity offset
* Added support for full-panning stereo option (Thanks to [Christopher Snowhill](https://github.com/kode54) for a work!)
* Fixed inability to play high notes due physical tone frequency out of range on the OPL3 chip
OPNMIDI 1.4.0 2018-10-01
* Implemented a full support for Portamento! (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
* Added support for SysEx event handling! (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
* Added support for GS way of custom drum channels (through SysEx events)
* Ignore some NRPN events and lsb bank number when using GS standard (after catching of GS Reset SysEx call)
* Added support for CC66-Sostenuto controller (Pedal hold of currently-pressed notes only while CC64 holds also all next notes)
* Added support for CC67-SoftPedal controller (SoftPedal lowers the volume of notes played)
* Resolved a trouble which sometimes makes a junk noise sound and unnecessary overuse of chip channels
* Volume models support taken from libADLMIDI has been adapted to OPN2's chip speficis
* Fixed inability to play high notes due physical tone frequency out of range on the OPN2 chip
* Added support for full-panning stereo option
ADL&OPN Hotfix: re-calculated default banks
The fix on side of measurer of OPL3-BE and OPN2-BE where some instruments getting zero releasing time.
Although this doesn't look as good as the PCF version it is a lot less calculation intensive and therefore more suitable for weaker hardware.
It also tends to bleed through walls a lot less.
