Christoph Oelckers	94e8d59dde	- implemented shader support for rendering the SW renderer canvas with legacy OpenGL.	2018-04-08 13:05:20 +02:00
Christoph Oelckers	df4f435952	- merged vid_renderer, swtruecolor and r_polyrender into one CVAR to reduce menu clutter. ... - with renderers freely switchable, some shortcuts in the 3D floor code had to be removed, because now the hardware renderer can get FF_THISINSIDE-flagged 3D floors. - changed handling of attenuated lights in the legacy renderer to be adjusted when being rendered instead of when being spawned. For the software renderer the light needs to retain its original values.	2018-04-07 23:30:28 +02:00
Magnus Norddahl	fde87c40d2	- fix crash when in software truecolor mode - the pitch is in pixels, not bytes	2018-04-07 19:56:54 +02:00
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
