lines: try adding CV output and filter cutoff interpolation
lines: try enabling rate multiplier / dividers
dsp: add linear and equal-power crossfading
lines: fix mul / div parameters. lo-fi pitch shifting works now
lines: add RQ slew
lines: fix rq slew time param
waves: finally make a proper 'voice' structure, add mix parameters, add filter slew. it compiles...
waves: added mix matrix, filter slew, etc. unfortunately, moving to the voice-structure model from the dumb "flat" model makes everything just a little too slow. dropped frames and etc. will probably revert this commit and start thinking about how to use the preprocessor better, use 16 bit mults, etc...
waves: killed shape modulation (sounded dumb anyways). instead got mix points back. each osc bus and adc channel mixed individually to outs 1+2, outs 3+4 get the same, no frame drops. next will do some aggressive optimization on matrix mixing and on param slew.

bfin_lib: macroize add/sub on fix16, its a start at least
bees: op_num is now op_bignum. gfx ops inherit from op_poll and have settable drawing rate. multiple bignum instances are supported but eat a lot of op pool memory.
bees: added op_screen for raw pixel drawing, totally retarded
bugfixes, edgemode, oplogic opis
add screen
Merge branch 'dev' of https://github.com/tehn/aleph into dev
commit the scene name bugfix? mid-work on lines unfortunately... will cleanup momentarily, for now use master
lines: compile with delay crossfade
lines: fix compile for realz
lines: fixed delay back to unfaded. hitting CPU limit computing 2x the phasors (?). will look into easy optimizations (e.g. mix matrix)
fix pan coefficients thing
lines: crossfade compiles...
