Blur damage tracking simplification (#155)

* suplified conditional in find_con_effect_iterator

* removed has_blur

* simplified optimized blur check

* moved damage expansion to output.c

* removed extraneous fx_renderer_scissor

* cleaned up render_output

* removed unneeded damage scale

* moved workspace optimized check function to workspace.c

* renamed ws iterator function

* added back region expansion

* removed uneeded parameter from get_main_buffer_blur

* returned extended damage

* moved get_blur_size back to original spot (reduce diff size)

* Fixed blur artifacting

* Fixed damage highlight not clearing correct framebuffer

* removed unneeded conditional

* moved initial damage expansion to output.c

* moved extended damage to the top of output_render

* moved blur damage to damage_surface_iterator

* ensure damage doesnt expand beyond output size

* removed stdint import
