Merge branch 'egil/egd_render' into ccase/r13b04_dev

* egil/egd_render:
  Fix egd_render transparent to use float constants

OTP-8425  Fix egd_render transparent to use float constants.

          The render engine has float guards to enhance beam code
          generation. However, the default case used integers which caused
          the engine to crash. This is now fixed.
