[RFC PATCH v2 0/5] Add support for text rendering

["Yordan Karadzhov (VMware)" <y.karadz@gmail.com>]

Implemented using the single-file public domain library "stb_truetype":
https://github.com/nothings/stb/blob/master/stb_truetype.h

PS: Patch 1/3 is a simple fix suggested by Slavomir which strictly
speaking is independent from the other two patches.

v2 changes:
  - 2 new patches (patches 4/5 and 5/5).

  - Added a procedure for finding a font file (patch 2/5).

  - Addressed the comments made by Slavomir in his review of the previous
  version.

Yordan Karadzhov (VMware) (5):
  kernel-shark: Simplify the drawing of the Triangle Fan
  kernel-shark: Add support for drawing text
  kernel-shark: Add text rendering to the plotting example
  kernel-shark: Add hello_kernel plugin
  kernel-shark: Drop Freeglut as a compulsory dependency
