Wrong button parameter 'pct' (should be 'saturate_pct')

[Valent-in]

All analog sticks has overlayX_descY_pct = 0.65 parameter which should describe stick sensitivity. But in fact this does nothing, because valid parameter name is overlayX_descY_saturate_pct = 0.65

This is 'reverse sensitivity': smaller value = more sensitive analog.
I think just 'fixing' param name in overlays or in RetroArch is bad idea because all analogs become too sensitive. Size of this button should be increased accordingly to saturate_pct value. Notice the image thumbstick-pad_arcade.png from 'flat' overlay pack - it already has transparent padding so visual size is smaller than actual hitbox. Is it designed for use with this parameter?
I think best value for this param is 0.5 - thumbstick image sticks exactly under touchpoint.

You can use online editor to test this. Default image set contains all images from RetroArch 'flat' overlays.

I used Notepad++ to do a "Find In Files" search for "_saturate_pct" in all ".cfg" files in the "overlays" folder and sub folders and got 0 hits.
Then I searched for "_pct" and got 51 hits in 21 files.

I also confirmed that it does in fact need to be:
E.g. overlay0_desc3_saturate_pct = 0.75 and not overlay0_desc3_pct = 0.75 in order to work.

Simple fix to retain the current behavior would be to change all occurrences of _pct = 0.XX to _saturate_pct = 1.00 so that people who are editing the files (Like I was) will know what the correct format to use is.
Or just delete the lines since they don't do anything.
