The blob generates following values for e.g. this call.
glBlendColor(0.002000f, 0.018000f, 0.030000f, 1.0)
0xff010508, /* [01424] PE.ALPHA_BLEND_COLOR := B=0x8,G=0x5,R=0x1,A=0xff */
etnaviv's etna_cfloat_to_uint8(..) creates different values.
0.002000: 0x0
0.018000: 0x4
0.030000: 0x7
The same applies for the alpha reference value.
Lets drop this hand-rolled conversion helper to get the same values as
blob.
