types.h was being picked up from webp rather than locally due to the
`include_directories` call for GTK (and therefore its -I arguments)
coming before the same call for the local sources. webp can be pulled in
via GTK -> gdk-pixbuf -> tiff -> webp.
This can be avoided by specifying `SYSTEM` or `BEFORE` as appropriate
when calling `include_directories`. I have done both for good measure.
This commit fixes the build error "unresolved external symbol GetModuleInformation" when the project is built on Windows with BUILD_SHARED_LIBS enabled.
Gzdoom must be linked against "psapi". When BUILD_SHARED_LIBS is off (default), it gets linked because the discord-rpc library is linked against it and then statically linked into the project. The issue is fixed by making Gzdoom itself explicitly link against "psapi" too.
This checked errno without first confirming that there has been an error, it is also pointless because the value range check will automatically catch the error case as well.
This is mainly for new games which have been designed for hardware rendering.
Note that this does not remove the software renderer's code - all it does is to disable the vid_rendermode CVAR by turning it into a static constant with the value 4.
Its only relevant use case has been to use the software renderer on hardware not capable of OpenGL 3.3, but a large chunk of that can now be serviced with GLES.
In addition it has ceased further development and has not received any of the recent 2D render features which further reduces its viability.
This is something that really should be done in higher level code - the shader interface should only concern itself with the shader and not the conditions that block its use.
The Shader class has been redone as a thin wrapper and been deprecated.
SSE_MATTERS formally went away in 466ed4e8f2, leaving behind this dead
branch that still needed to happen for 32-bit targets. It was further
broken later with some path restructuring.
