Christoph Oelckers	cd00f1fb45	- fixed incorrect check for SW texture recreation.	2018-04-07 18:41:25 +02:00
Christoph Oelckers	211a7f2569	- made the screen blend work for the software renderer. ... It may use the same calculations as the hardware renderer but must use the 2D drawer for display. It should be investigated if the hardware renderer can do this as well.	2018-04-07 10:53:20 +02:00
Christoph Oelckers	b34d7f9e08	- added a software scene drawer to the GL renderer. ... It still looks like shit and only works on the modern render path but at least the basics are working.	2018-04-07 10:20:59 +02:00
