- remove obsolete svn '$Id$' tags from all source files - update .fl files and generated files accordingly - replace 'http://www.fltk.org' URL's with 'https://...' - replace bug report URL 'str.php' with 'bugs.php' - remove trailing whitespace - fix other whitespace errors flagged by Git - add and/or fix missing or wrong standard headers - convert tabs to spaces in all source files The only relevant code changes are in the fluid/ folder where some .fl files and other source files were used to generate the '$Id' headers and footers.

// This is a test of the minimal update code. The right slider has a
|
|
// label that extends outside its border, and the minimal update
|
|
// assumes this does not happen. Thus there is *supposed* to be
|
|
// display errors when you move the right-most or any other slider.
|
|
// If you *don't* see these errors, then the minimal update is
|
|
// broken!!!
|
|
//
|
|
// I cannot emphasize how important it is to test this and make sure
|
|
// any changes have not broken the minimal update. These sort of bugs
|
|
// are extremely hard to fix and must be detected right away!
|
|
//
|
|
// The reason it is important to fix this is that otherwise you will
|
|
// swiftly end up with a toolkit that thinks it has to draw the window
|
|
// 20 times each time the display changes. I don't care how fast the
|
|
// machine is, this is an insane waste of resources, and should be
|
|
// stopped!
