Scissor test implementation. Partially stubbed until geometry shaders… (#556)

Browse source 
* Scissor test implementation. Partially stubbed until geometry shaders are fixed

* Apply to all viewports when geometry shaders are disabled.

* Also apply enable cap to all viewports when geometry shaders are disabled

* Added fixme as per suggestion

Co-Authored-By: BaronKiko <BaronKiko@users.noreply.github.com>

* Apparently no alignment needed here.

* Comment on new line

* Correct height calculation
