Looked at the placebo.Shader parameters:

float radius
// Contains the true radius of the computed filter. This may be
// larger than `config.kernel->radius` depending on the `scale` passed to
// pl_filter_generate. This is only relevant for polar filters, where it
// affects the value range of *weights.
which are polar filters?

float clamp
// Represents a clamping coefficient for negative weights. A value of 0.0
// (the default) represents no clamping. A value of 1.0 represents full
// clamping, i.e. all negative weights will be clamped to 0. Values in
// between will be linearly scaled.
default ?


float taper = 0.0
// Additional taper coefficient. This essentially flattens the function's
// center. The values within [-taper, taper] will return 1.0, with the
// actual function being squished into the remainder of [taper, radius].
// Defaults to 0.0.
min? max?

float blur
// Additional blur coefficient. This effectively stretches the kernel,
// without changing the effective radius of the filter radius. Setting this
// to a value of 0.0 is equivalent to disabling it. Values significantly
// below 1.0 may seriously degrade the visual output, and should be used
// with care.
default? min? max?

float param1
float param2
float antiring = 0.0

int lut_entries = 64
// The precision of the resulting LUT. A value of 64 should be fine for
// most practical purposes, but higher or lower values may be justified
// depending on the use case. This value must be set to something > 0.
Min? Max?


float cutoff = 0.001
// Contains the effective cut-off radius for this filter. Samples outside
// of this cutoff radius may be discarded. Computed based on the `cutoff`
// value specified at filter generation. Only relevant for polar filters
// since skipping samples outside of the radius can be a significant
// performance gain for EWA sampling.
-> Which of the filters are polar filters? only the ewa_* (elliptical weighted average) filters?

Still there are too much unkown things to support the options,..
