I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.
If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces. For example, to see
per-line authors, use "git blame -w <file>". Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".
choose to print to pdf as well. Also, enable the preference
under linux (ie, make it available to be chosen-- all platforms
still default to printing via the platform-specific mechanism)
Added lambda icon, foot icon, search forward/back icons
Doc fixes
Stepper: icons on buttons, logo and about dialog
Macro stepper: icons on buttons, logo and about dialog
Please merge into release
This is a backwards incompatible change; there is a more complex change
that just stubs this stuff out that may be better that we may need
isntead of this commit.
