…on Intellij's (Android Studios'?) project structure

- Removed some hungarion notations
- Added some static imports
- Simplified some code and removed comments
- Added braces and made fields private

 - Converted methods comments into javadoc
 - Removed redundant comments
BatchTextProgram:
  - Extract vertex and fragment shaders to glsl files
RawResourceReader:
 - Created a class to read glsl files to String

 - Moved null check on program to a static method to instantiate BatchTextProgram
 - Removed redundant comments
 - Made variable names more explicit
 - Changed method comments into javadoc

 - Moved methods in Utilities to Program
GLText:
 - Trying to minimize the load method by extracting code to methods
SpriteBatch:
 - Created an inner class Vertex to remove some code duplication
Triangle:
 - The triangle class was unused, removing it to focus on font rendering
Vertices:
 - Comments to javadoc

 - Extracted method
Removed unused Utilities class

…sary Android classes to run the example.

By moving the remaining classes to a separate package and making them package private it is obvious GLText is our main domain class.
It also contains a lot of code, so next I'll experiment with splitting up instantiation logic from rendering logic etc.

AndroidManifest:
 - Removed debuggable=true as per Android Studio warning
 - Removed uses-sdk, this is defined in the build.gradle
build.gradle:
 - Incremented API version to 22, git gud scrubs

…ptions, resulting in the AVD crashing.

This change is less intrusive, moving the domain classes into a separate package and making them all package local except GLText

 - Made CHAR_BATCH_SIZE private, it was used in SpriteBatch to intialize the mvpMatrices array, moved that to the constructor since CHAR_BATCH_SIZE is passed as maxSprites paramter
 - Replaced static factory method with static builder
 - Rearranged some methods
Texample2:
 - Moved GLSurfaceView implementation to its separate class: Texample2SurfaceView
Texample2Renderer:
 - Moved division of width and height to the drawTexture method, since it is used inside the method to draw the texture centered

…eless. This makes them easier to move to GLTextBuilder.

- Moved fontHeight, fontAscent and fontDescent into a separate FontMetrics class
- Moved assets to GLTextBuilder, passing Typeface instead

…tuts/enhanced-drawing-painting

…nt into a separate FontTexture class

 - Removed hungarian notation
 - Removed redundant comments
 - Using StreamSupport to use streams and still have backwards compatibility with lower APIs
 - Rewrote comments to javadoc
 - Inlined redundant variables
FontTexture:
 - Removed redundant comments
 - Renamed some variables

 - Moved charWidths and charWidthMax into a FontCharacters inner class
 - Removed unused methods
 - Experimenting with a builder pattern for drawing

…value object to hold the program handles used by Font

 - Added support for AttributeVariable
UniformVariable:
 - similar to AttributeVariable, used in conjunction with glGetUniformLocation
Program:
 - moved logic in init method to constructor
 - removed initialized field variable
