Implemented a batching procedure, to try to group meshes in a buffer
and use a final GL call to draw them all in one step, instead of the
many GL draw calls existing today.
For now, only 2D textures are included, especifically console text
("conchars"), scrap and tiles. It's not worth doing this for
individual 2D elements (e.g. crosshair).
They were in this form:
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG/MIN_FILTER,GL_LINEAR)
Only appeared at startup, but we didn't need so many of them.
ref_gl renders use 0.0..1.0 float texture coordinates in gl commands
and skin ratio/resolution could be any.
ref_soft render uses absolute coordinates as result textures with
different to expected size are applied incorrectly.
Fix will not add support of scalled retextured skins, just fix case
when ratio is incorrect after scale down such or place a incorrect
pcx skin to the model directory.
The first try didn't take into account that an evil server could
override the filter list by sending a stuff command. Fix this by
hardcoding the filters for .dll, .dylib and .so. Make sure that the
filters are always applied, either when the download is requested
through the `download` command or because game data is missing.
This is just a poor mans fix, trying to rule out an obvious way to
inject code into the client.
`cl_nodownload_list` is a whitespace seperated list of strings, files
containing one of these strings in their name are never downloaded. Set
to `.dll .dylib .so` by default to prevent downloading libraries which
can be injected into client.
Closes#1114.
It will be used in a later commit. While at it change Q_strcasecmp() and
Q_strncasecmp() to take the arguments as const, matching the signatures
of the non-replacement versions.
Applied too many OpenGL calls for an effect that could not be told
apart from normal GL_MODULATE; explains its absence from Q3A code.
Also, removed calls to glPixelStorei when no dynamic lights present.
With "hand 2" and no "alias" models in player sight, sometimes only
lightmap was visible. Now forcing disabled multitexture when needed.
Another bugfix: "gl_showbbox 1" no longer produces OpenGL errors.
Controlled by gl1_biglightmaps cvar, works like new lightmaps.
Max size is 384x384; a bigger size is not justified.
Added a transparent border so colors from one picture don't bleed
into the next.
Controlled by new cvar, gl1_biglightmaps.
Size is now up to 512x512, for a max quantity of 8 lightmaps.
Should reduce rebinding of them, and reduce the number of calls
to glTexSubImage2D(), although it may increase data transfer on
each call.
Only happens in Windows. A cvar was being queried just after
all cvars were freed, in Qcommon_Shutdown().
GL_GENERATE_MIPMAP definition relocated.
scrap_uploads counter deleted, it wasn't being read anywhere.
