Prevent Resizer if unsupported filter option is given

[matdave]

Resizer only supports fltr[]=usm, fltr[]=wmt, and fltr[]=wmi. It would be nice to have a check that looks to see if any of the other filters are being used and override the Resizer option.

Other Filter Options:

• stc
• blur
• gblr
• sblr
• bord
• crop
• ric
• sat
• ds
• clr
• gray
• sep
• mask
• drop
• elip
• flip
• bvl
• fram
• neg
• th
• rcd
• hist
• lvl
• wb
• edge
• emb
• mean
• smth
• gam
• brit
• cont
• over
