From: chandra konduru <chandra.konduru@xxxxxxxxx> This patch is adding i-g-t plane scaling test case to test couple basic display plane scaling usages. Additional test scenarios can be added later. v2: -Added iterative scaling to visually observe scaling (me) v3: -Added a flag to control primary plane scaling.
