Changed how polygonbegin guesses if the geometry is 2D or 3D, it now uses a separate variable rather than relying on r_refdef.draw2dstage.
Reworked DrawQ_* and R_RenderView code to make clear distinctions between 2D and 3D code, this removes a lot of unnecessary calls to DrawQ_FlushUI (including ones that happened in R_RenderView).
Added R_DebugLine which takes a line in world coordinates and adds it as a 2D line in CL_Mesh_UI.
Added r_showparticleedges and r_showspriteedges debugging cvars which make use of R_DebugLine.
Added v_isometric cvars, this mode is mostly a curiosity but it's useful for testing engine compatibility with non-perspective rendering.
Fixed a few bugs where distance culling was misbehaving with non-perspective rendering.
Make r_refdef.view.ismain more useful - it's now cleared after R_RenderView rather than before, so R_RenderView can make use of it (for r_motionblur ghost texture updates and anything else that wants to happen just on the main view).
Added r_cullentities_trace_expand and pad cvars, these configure additional ways to expand entity boxes when culling by traceline.
Added r_vis_trace feature which allows you to turn on traceline-based culling of portals, and r_vis_trace_surfaces lets you cull surfaces by traceline (slow and probably pointless, but a curious feature).
Added r_shadow_culllights_trace_expand and pad cvars.
Added sv_cullentities_trace_expand to make SV_CanSeeBox be at feature parity with R_CanSeeBox.
Enable PRVM_64 - the QuakeC VM will run as 64bit (using int64/double rather than int/float).
This means that levels can run for > 10 hours without time precision issues, and float flags values can have flags ranging up to 54 bits rather than 24 bits.
There may be bugs, and physics is still using 32bit floats in a bunch of places so this does not enable huge worlds currently.
Made RENDERPATH_GL20 require fbo support and always use it.
Implemented R_RenderTarget system for managing fbo and texture requests dynamically, reusing the same ones across frames - this means that the textures are now allocated much smaller and there is better handling of multiple CSQC viewports.
In the short-term this means that vid_samples antialiasing doesn't do anything, it will need to be reimplemented using fbo.
Fix some viewport issues with r_viewfbo and r_bloom by passing view size information when calling the various rendering subsystems - there are still a bunch of bugs but this is a temporary measure before rendertargets are put in.
CSQC polygonbegin functionality now uses the CL_MeshEntities system, this finally makes it possible to use shaders on those polygons.
UI elements (DrawQ_ system) now use the CL_MeshEntities system, but still renders the mesh the old way, shader support is planned.
DrawQ_Line no longer uses GL_LINES, it now produces a polygon in the CL_MeshEntities system, so shownetgraph and r_speeds_graph features now work on D3D9/DPSOFTRAST/GLES2 render paths.
Added MATERIALFLAG_VERTEXCOLOR as a special case for rgbgen vertex shaders that are being used by CL_MeshEntities meshes, currently this is an unlit type of material but lighting support for it is planned.
Added Draw_GetPicWidth, Draw_GetPicHeight, Draw_IsPicLoaded functions and moved cachepic_t to live in gl_draw.c (no longer visible to other modules).
Changed Draw_CachePic to use the R_SkinFrame_LoadExternal system, and reworked font loading to use Draw_CachePic rather than keeping track of textures itself. R_SkinFrame_LoadExternal can now load gfx.wad lumps and gfx/*.lmp files, and the embedded images have been moved to image.c as they are now returned as raw images, suitable for R_SkinFrame_LoadExternal to use.
Reworked cl_video code to not need the cl_dyntexture system (which has been removed); it still uses dynamic texture callbacks (which is a feature of rtexture_t).
Changed the parameters to Mod_LoadCustomMaterial and a few other model_shared.c functions to not assume loadmodel is the owner of memory and textures; this was necessary for Draw_CachePic to be able to use R_SkinFrame_LoadExternal.
Refactored R_UpdateEntityLighting to CL_UpdateEntityShading, which sets fields like ent->render_modellight_ambient.
Added texture->render_modellight_ambient and similar fields which concretely define how the material is to be rendered, so all of the various tweaks and modifiers are no longer buried in R_SetupShader_Surface which has now been refactored heavily.
Removed R_LightPoint as it's really not necessary - this change will make lit particles a little bit slower as R_CompleteLightPoint is a slightly more expensive function.
Refactored R_CompleteLightPoint to have more consistent code, changed the final color math so that it passes q1bsp/q2bsp lighting through unmodified.
Changed shading of tag_entity attachments - they now use the root entity's origin for shading, this fixes r_shadows where the shadows could go in different directions on CSQC entities (r_shadows code already contained a hack to work around this problem for network entities).
Renamed r_refdef.lightmapintensity and ambient to r_refdef.scene.lightmapintensity and ambientintensity.
Change default value of r_shadows_shadowmapscale from 1 to 0.25, so that
shadows cover a larger part of the level around the eye.
Change the way r_shadows 2 size is calculated so that it uses 1/4th of
the texture atlas size (at default this would be 2048 of 8192) rather
than 2*r_shadow_shadowmapping_maxsize (at default that was 2*512 = 1024
of 8192).
Make the semantics of CL_VM_UpdateView more clear - if CSQC is loaded, it is required to provide the CSQC_UpdateView function, and won't render a view if it does not call that, so we don't need to check its return value.
New alternative to fullbright: r_fullbright_directed.
Set this to 1, and anything EF_FULLBRIGHT or fullbright due to
r_fullbright or unlit map (but specifically not sprites and surfaces
with surfaceparm nolightmap) will have a directional effect applied to
them.
This mode is intended for testing maps in early development, and should
not be used for normal gameplay (although it should be rather harmless
there).
Manage resetting the key event state on video reinitialization centrally.
Fixes:
- No key state clear when SDL gets restarted.
- Key state clear was the wrong action - it allows all keys to get pressed
again, but does not actually release anything in cl_input.c, so e.g. +jump
binds stay pressed on vid_restart.
Only vid_wgl.c retains some vid-specific handling (reset of key state when
alt-tabbing out and back in) - there's a chance that we may need similar logic
in the other vid drivers; if so, it may be possible to do this in a shared
place too by watching for changes to vid_activewindow.

Make TraceLineOfSight check if the trace endpos is within a box, not just if fraction is 1 - this makes it much more likely to say an object is visible when the object overlaps walls and other obstacles as the rays only need to reach the box, it doesn't matter much where it goes inside the box.

Change shadowless rtlights so that they are not occluded by anything - no pvs checks or portal culling.
This makes r_shadow_deferred 0 look the same as r_shadow_deferred 1 - lights fill their whole area if there are no shadows to block them.
This also fixes a popping issue with r_shadow_deferred 1 where the eye was not in a leaf the light considered to be visible, and thus the light was not drawn (which made quite a difference when you move back and forth between leafs that were and were not lit), since when it was drawn it lit everything in the area.

Use the invariant keyword on gl_Position on GLSL 1.20 or higher and GLSL ES

SDL2: combine SDL_KEYDOWN events directly with following SDL_TEXTINPUT events when possible.
This solves ` keypresses that open/close the console also typing in a character
"once and for all". The ability to type the ` character into the console is not
impaired by this as con_closeontoggleconsole's logic to by default ignore the
toggleconsole key when in the console but not at the beginning of the line
still applies.
rcon server: add an explicit check against empty password, instead of assuming the calling code is correct.
This logic had a bug in the past that had been introduced by r8886 and
accidentally fixed when introducing multi-account support in r9420. The bug was
that rcon_password being empty led to the empty password being accepted in some
cases, as there was never any explicit logic to handle that in rcon - it was
more "accidentally" rejected by a packet formatting check which does not apply
to srcon as the empty password wouldn't be empty over the wire.
In other words: DP builds from [r8886, r9419] had a serious vulnerability and
the only workaround is to always have rcon_password set.
The check added here will complain and reject in case the calling code for some
reason no longer prevents empty passwords from being accepted.
Also adding comments to the new logic explaining how it prevents the empty
password from being accepted.
Fix a bug in collisions between brushes and brushes when the plane is rotating - this case is never used currently but it's definitely a bug worth fixing.
