the main reason for doing this is so that we can have
access to informations about a texture (like its dimension)
close to where we generate and use shaders in ES 2.0.
Previously, there wasn't any way to get to a texture's size
from a RenderEngine implementation.

- turns out fragment shaders don't have default precision by default
- GLES 1.x extensions that became core in GLES 2.0 don't always work
as extensions in GLES 2.0 (!)

this is the first step to add support for GLES 2.x, this
change breaks the dependency of SF on GLES 1.x by moving
all operation into their own class.
