Without this, some code will enable (and set other parameters for)
whatever random texture unit the previous stage had selected. This can
break any fixed-function rendering, since either it will not have
enabled the correct texture unit, or its correct setup will be
interfered with by another texture unit that shouldn't be enabled. (This
doesn't affect ARB/GLSL shader rendering, since they don't care about
the enabled state, but the GUI (and some debug things) are still FFP in
the default ARB mode.)
Fixes#2833 (in which the fancy water shader selected texture units 5/6,
which then got enabled, and remained enabled forever).
This was SVN commit r16372.
This fixes the problem where passing a non-ASCII string to
debug_printf(L"%hs", s) caused vswprintf_s to fail on Linux (because it
doesn't know what encoding the char* is meant to have). Now debug
messages will remain as UTF-8 until they reach the OS.
Fixes#3021.
This was SVN commit r16332.
Some drivers (at least the Intel drivers on Windows) are slow at
incrementally updating a VBO with hundreds of calls to glBufferSubData
every frame. Performance is significantly better if you use
glBufferData(NULL) to tell it to discard all the previous contents, and
then re-upload all the data at once.
Update CVertexBuffer so that GL_DYNAMIC_DRAW/GL_STREAM_DRAW buffers are
handled with the new mechanism. This requires the caller to hold onto
the backing store so it can be re-uploaded when necessary, and needs a
bit more signalling to indicate exactly what needs uploading.
I see an improvement from roughly 60 to 75 fps on Intel HD Graphics
3000, Windows, 1024x768, Siwa Oasis.
This was SVN commit r16241.
This upgrade also introduces exact stack rooting (see to the wiki:
JSRootingGuide) and fixes problems with moving GC. This allows us to
enable generational garbage collection (GGC).
Measurements a few months ago have shown a performance improvement of a
non-visual replay of around 13.5%. This probably varies quite a bit, but
it should be somewhere between 5-20%. Memory usage has also been
improved. Check the forum thread for details.
Thanks to everyone from the team who helped with this directly or
indirectly (review, finding and fixing issues, the required C++11
upgrade, the new autobuilder etc.)! Also thanks to the SpiderMonkey
developers who helped on the #jsapi channel or elsewhere!

Everything is char* now, so we don't need to mess around with different
string types.
Done with:

-pi -e'1 while
s/(LOG(MESSAGE|MESSAGERENDER|WARNING|ERROR).*)%[hl]s/$1%s/g'

This was SVN commit r16183.
sys_vswprintf relies on platform-specific printf implementations, which
vary widely between platforms (in handling of truncation, return values,
use of %s/%S/%hs/%ls for mixing char and wchar_t strings, etc) and are
therefore a pain.
Use cppformat's fmt::sprintf instead, which has very similar syntax to
sprintf but is more C++ish and is portable.
Also, wchar_t is stupid, so use char* strings (which are expected to be
UTF-8) in CLogger. This creates a bit of a pain with changing all
callers to convert to char* strings, but that's their fault for not
using UTF-8 already.

Fix Engine.ReadJSONFile() which did throw a JS exception that was not
caught. Discovered by s0600204.
Expose Engine.ReadJSONFile() to the gui scripts.
This was SVN commit r15959.
Changes GetProperty, SetProperty and HasProperty and a few other
functions to take handles. The conversions to CScriptVal or
CScriptValRooted at some places should be removed in the future. I've
done that to avoid an even larger patch.

Do some intersection tests on the CPU so that the silhouette render
passes only have to draw models/patches that might actually contribute
to silhouettes, saving the CPU and GPU cost of rendering more objects
than necessary.
This was SVN commit r15483.
Remove commented out code writing triggers that has nothing to do with
the actual triggers implementation.
Free memory that was allocated for error reporting when when fork()
fails.
Remove dead initialization.
This was SVN commit r15477.
Previously we had a single culling frustum based on the main camera, and
any object outside the frustum would never get rendered, even if it
should actually contribute to shadows or reflections/refractions. This
caused ugly pop-in effects in the shadows and reflections while
scrolling.
Extend the renderer to support multiple cull groups, each with a
separate frustum and with separate lists of submitted objects, so that
shadows and reflections will render the correctly culled sets of
objects.
Update the shadow map generation to compute the (hopefully) correct
bounds and matrices for this new scheme.
Include terrain patches in the shadow bounds, so hills can cast shadows
correctly.
Remove the code that tried to render objects slightly outside the camera
frustum in order to reduce the pop-in effect, since that was a
workaround for the lack of a proper fix.
Remove the model/patch filtering code, which was used to cull objects
that were in the normal camera frustum but should be excluded from
reflections/refractions, since that's redundant now too.
Inline DistanceToPlane to save a few hundred usecs per frame inside
CCmpUnitRenderer::RenderSubmit.
Fixes#504, #579.
This was SVN commit r15445.
Instead of each CCmpVisualActor rendering itself individually, collect
all the units in a single CCmpUnitRenderer. This avoids the overhead of
doing Interpolate/RenderSubmit calls every frame for every object in the
world. It also allows more efficient culling.
CCmpUnitRenderer knows the positions of each object at the start and end
of each turn, and computes the bounding sphere of the object along that
path. That allows quick culling without recomputing the precise
interpolated transform every frame. (In the future it could be improved
much more.)
Clarify and clean up the sending of PositionChanged messages, and add
new InterpolatedPositionChanged.
Remove the forceFloating parameter from GetInterpolatedTransform, since
it doesn't fit the new design. Replace it with a (non-synchronised) flag
in CCmpPosition.
Move construction progress from CCmpVisualActor to CCmpPosition, so that
it consistently affects all position/transform computation.

This was SVN commit r15265.
This allows component Init functions to make use of the terrain
immediately, instead of delaying some computations until the first
frame.
This was SVN commit r15262.
BoundingSphere is similar to a bounding box, but more spherical.
SOverlaySphere is useful for visualising BoundingSphere (it's quite
inefficient and should only be used for debug functionality).
Normalise the camera frustum clipping planes, so that IsSphereVisible
gives the correct result.
This was SVN commit r15261.
For unknown reasons, sometimes glTexSubImage2D acts as if
GL_UNPACK_ALIGNMENT = 2 or 4, instead of 1. This causes the odd-sized
array uploaded for the LOS texture to be interpreted incorrectly, and
the LOS texture gets rendered very incorrectly.
Pad the array to a multiple of 4 in all cases, so that
GL_UNPACK_ALIGNMENT shouldn't affect it.
Hopefully fixes#2594.
This was SVN commit r15216.
The tests crashed on my Debian systems but not on my Ubuntu system.
The crash happened in line 142 of SpiderMonkey's ThreadLocal.h.
I know that I had to use a workarounnd for contexts to avoid destroying
the context that was created first. I also had in mind that in newer
versions a JS_Init function got introduced which presumably solves this
kind of issues.
Based on this experience I assumed runtimes could have a similar problem
and this patch indeed fixes the issues.
Unfortunately the correct usage of JSRuntimes in that regard is not
documented.
There's only a rater misterious comment in JSAPI.h which hasn't been
cleared up so far and is most likely completely outdated
(https://bugzilla.mozilla.org/show_bug.cgi?id=992641).
This was SVN commit r14995.
This commit contains all the required changes to our source files and
build scripts (hopefully).
A next commit will remove the old stuff of SpiderMonkey 1.8.5.
