* This is the code that renders the letter a for each vertex on the mesh paired with a libigl-example-project
* Code for rendering just the number 12 on the 12th vertex
* Rendering vertices via glsl works, with geometry shader
* Added dynamic font scaling so accomodate ortho and perspective projections.
* Got faceids rendering
* Code cleanup
* This allows user to add custom text at some location rendered with the text shaders
* Dedicated separate VBOs for face and vertid labels
* Added in extra label rendering
* Moved texture binding to its own function and other code cleanup
* More conflict resolution when fetching upstream changes
* Resolved the relative path to font atlas
* Change scope variable for font atlas macro
* Removed PNG texture loaded from disk, and encoded font atlas into byte array. Other minor changes for VBO iterators and removed uneeded dependencies from previous commits
* Encapsulated text VBOs into struct to remove code duplication, and fixed bug for both overlay and text shaders being used at same time.
* Remove whitespace
* Tentative for Windows build fix not initializing TextGL structs in header
* Removed uniform that only belongs for text labels
* Added init and free methods for label buffers initialization and passing some args by reference on label methods
* Compressed font atlas that is under 50kB reduced from 330kB with decompression function
* Converting type from string literal to char array
* Broke up string literal
* Cleanup font atlas.
* Linux compile fix.
* Remove deprecated text pipeline.

Now viewer menu can be overriden with lambda function (for simple
override), or virtual methods (for more complex situations).
