Pan tapers
Add pan tapers to pan law selection

Reaper uses a very odd pan taper. To bring it more in line with other DAWs I'd suggest adding a pan taper selection to the current pan law selection (as a second listbox. maybe the compensated/uncompensated could also be turned into a checkbox, which would halve the length of the pan law list -- and be slightly less confusing for beginners methinks).

The pan tapers would be:
Reaper (which should be the default, as this might otherwise break older projects / workflow for new projects)
Square-root
Sinusoidal

If you are about to complain, that both square-root and sinusoidal tapers are fixed to a -3 dB law, they can easily be extended as so:

P = Pan amount [0:1] (0 = left, 0.5 = center, 1 = right)
L = Pan law (reduction at center in dB, must be unequal 0dB. example -6dB => L = 6)

For square-root (or maybe it should be called exponential):

Ch1 = (1-P)^(L/6)
Ch2 = P^(L/6)

For -3 dB we get the standard square-root taper and for -6 dB a proper linear taper.

The sinusoidal law could be adapted in the same fashion:

Ch1 = sin(0.5*pi*(1-P))^(L/3)
Ch2 = sin(0.5*pi*P)^(L/3)

For -3 dB the result is a regular sin/cos taper, and for -6dB we get a squared sinusoidal taper.

Other tapers would be possible as well, such as piecewise linear which would approximate how actual potentiometers are built.

Just in case it isn't obvious from the FR, the 0dB pan law would remain as is no matter what taper is chosen, as it isn't actually a pan mode but a balance mode.
