TID-31/new bit map font rendering

[ravi688]

All the resources and data structures have been setup to make bitmap text rendering feasible and now it's working. However following are the things yet to be done/added:

• Use screen projection matrix to scale the text correctly whenever the window is resized.
• Add a text string bounding box and wrapping the text into the next line.
• Add text alignment options, such as left, middle, and right.
• Add kerning support.
• Improve the quality of the smaller bitmap texts.
