[Piglit] [PATCH 07/13] shader_runner: Create an ES context if test requests one

Mon Dec 3 21:59:35 PST 2012
If the tests lists a requirement for an OpenGL ES context, then set
piglit_gl_test_config::supports_gl_es_version appropriately. If the test
lists no requirement for OpenGL ES, then no behavior is changed.
For example, if the test contains:
[require]
GL >= 3.0 es
GLSL >= 3.00 es
Then:
config->supports_gl_es_version = 30;
This patch added enough complexity that I chose to refactor
get_version_requirements() into three stages:
1. Move the parsing into new function parse_version_requirements().
2. Move the selection of GL version into new function
choose_required_gl_version().
3. Leave the setting of piglit_gl_test_config::supports_gl_*_version
in place in get_version_requirements().
