The Renderscript fragment program, also known as fragment shader is responsible
for manipulating pixel data in a user defined way. It's constructed from a GLSL
shader string containing the program body, textures inputs, and a Type object
that describes the constants used by the program. Similar to the vertex programs,
when an allocation with constant input values is bound to the shader, its values
are sent to the graphics program automatically.
The values inside the allocation are not explicitly tracked. If they change between two draw
calls using the same program object, the runtime needs to be notified of that
change by calling rsgAllocationSyncAll so it could send the new values to hardware.
Communication between the vertex and fragment programs is handled internally in the
GLSL code. For example, if the fragment program is expecting a varying input called
varTex0, the GLSL code inside the program vertex must provide it.

ProgramFragmentFixedFunction is a helper class that provides
a way to make a simple fragment shader without writing any
GLSL code. This class allows for display of constant color, interpolated
color from the vertex shader, or combinations of the both
blended with results of up to two texture lookups. |

ProgramVertexFixedFunction is a helper class that provides a
simple way to create a fixed function emulation vertex shader
without writing any GLSL code.
