Fix the problem of memory leak in gradient pixmap generating. The problem caused by we do not call glDeleteShader when destroy a shader program. This patch will split the gradient pixmap generating to three category. If nstops < 6, we will use the no array version of the shader, which has the best performance. Else if nstops < 16, we use array version of the shader, which is compiled and linked at screen init stage. Else if nstops > 16, we dynamically create a new shader program, and this program will be cached until bigger nstops. Signed-off-by: Zhigang Gong <zhigang.gong@linux.intel.com>
