FTGL is used for font rendering and FTGL uses the FreeType library for fonts.  FTGL contains a header file named FTGlyph.h and FreeType contains a header file named ftglyph.h and they are the same name but differ only in capitalization.  The Apple Mac file system is case insensitive and this name clash results in compilation problems on Mac OS X 10.10 Yosemite.  FTGL FTGlyph.h has been renamed to FTGLGlyph.h to fix this problem as described in http://sourceforge.net/p/ftgl/bugs/41/.   Also note that FreeType's ftglyph.h is not used directly but is defined with the macro FT_GLYPH_H.

ProgressReportingDialog: It appears that when the progress dialog's content, as seen by the user, only updates when the progress value changes and NOT when the label's text is changed.  So, when the progress event is received, update the label's text first and then set the progress value.  This should fix a problem with the dialog's label text being 'one event behind' the most recent event.

ProgressReportingDialog now defaults progress range to [0, 100] which should result in it being displayed sooner.

When a new border is created, call Border::setClosed(true) for a a closed border and Border::setClosed(false) for an open (not closed) border.

remove the path from the filename in border optimize progress, add a progress step for making the geodesic helper

Create a ProgressReportingDialog when running border optimize so that the user can see the progress and have the option to cancel.  Removed the wait cursor since the progress dialog indicates work is in progress and the progress dialog closes when border optimization completes.

Border Optimize Dialog: Default number of data files to the the greatest of 10 or the actual number of data files.

Border Optimize Dialog: Create a new overlay at "the top" to which the gradient metric file is added.

Border Optimize Dialog: Enable exclusion radius spinbox for only dense files, disable skip gradient checkbox for dense files.

add smooth data-following capability and use it, sanity checking in SurfaceFile, make geodesic heuristics consistent when using corrected vertex areas

Border Optimize Dialog: Add exclusion distance, skip gradient to data files.  Resolve some sizing and layout issues.

Fixed operation of Information Window Clear and RID buttons to match HCP 1.0 Tutorial.  Clear removes text but identification symbols remain on surface/volume.  RID removes identification symbols but text remains in information window.

Add ability to preserve a dialog's size when reopened in WuQDialog and use with BorderOptimizeDialog.

Revised logic for disabling map selection for Dense file in border optimized dialog.  If a Dense file is selected, deselect and disable the "all maps" checkbox.

Disable map selection when the selected file is a DENSE file in border the Caret File Selector used by the border optimize dialog.

For gradient metric file produced by border optimize algorithm, set the palette to: videen_style, 4% to 96%, positive values only, interpolation on.

Border Optimize Dialog: (1) Added Enable/Disable all buttons for all borders; (2) Added Enable/Disable buttons for all data files; (3) Add option for keeping the enclosing (temporary) border that is defaulted on; and (4) Display a wait cursor after user pressed the OK button until border optimization finishes.

Border Optimization Dialog: (1) Smoothing label includes "sigma", (2) "Undo Finish" now functions, (3) Combined Gradient produced by the algorithm becomes the top-most overlay after algorithm completion.

Add GUI controls for vertex areas metric file and gradient following strength to Border Optimize Dialog and inputs for the algorithm.

Forgot to add the new files (BrainOpenGLVolumeObliqueSliceDrawing .h/.cxx) to GIT before the last commit.

Renamed OLD_BrainOpenGLVolumeSliceDrawing to BrainOpenGLVolumeObliqueSliceDrawing.  A previous issue (volume centering) was implemented for orthogonal slice drawing but broke oblique slice drawing so the existing oblique drawing was moved to a separate file and will be updated with volume centering when time permits.

Partial implementation of WB-499 Should Volume ID Place a Symbol: Identification symbols for volume identification have been added but some issues remain including (1) should a node (voxel) identification also identify the corresponding voxel (node); (2) Should Identify Window Clear button remove only text but leave symbols, and (3) Should RID remove symbols but leave text.
