Reworked the lantern and buildings to use the libraries.
Lamp Post: Included by buildings if lamps should hang outside.
Lamp: Included by lamps!
Lamp Dummy: Included by the dummy object that resembles the (outisde) hanging lamp.
Covers are foreground objects to hide behind. Covers become invisible once your (crew) cursor is behind it, effectively turning them into a good place to hide.
CastObjects returns an array now, so that further function calls can be issued on the created objects.
(cherry picked from commit 184943fe6f720ba26402764bb3b182d550370e74)
GetSurfaceVector() and the Coral object now use the array format of the vector library for vectors, instead of proplists.
(cherry picked from commit 03f644e56cdc99a84df57451ed1bac361c0c896d)
Color value is now uint32_t, removed superfluous conversion to unsigned value, simplification in the shader.
Open: C4DP_Last and number of drawing passes
The color of object lights can now be changed. This includes the following changes:
- added light test scenario, based on DarkCastle, with some lights,
- new functions SetLightColor() and GetLightColor() with C4Script documentation,
- third drawing pass for rendering the light color, the drawing passes are now referenced by enum,
- the blending of light from multiple colored light sources works correctly with alpha blending,
- light color value affects the intensity of the light,
- alpha blending of the light depends on color value and lightness. This means that brighter (= more value) and lighter (= more whiteish) light will be preferred in blending over other lights,
- the object light color is rendered to the lower half of the fow light texture now,
- the shader accesses the brightness/direction information and color information correctly,

Several rendering changes have resulted in a non-rendering build that
failed to build from source. Dummy out all of these functions to make it
work again.
On success, flock() returns 0, so !flock() is true then. Testing for
!flock() to detect a locking error is therefore wrong. This got the log
file closed immediately after opening it on my GNU/Linux machine,
resulting in an always empty OpenClonkShader.log.
I'm sure there was a reason to have a separate DebugLog function inside
C4Draw, with a different visibility trigger, but I don't see it. Also
there was no DebugLogF, so that's fun too.
OpenClonk supports debug contexts on both Windows and Linux now. Start the
engine with the argument --debug-opengl to request a debugging context and
marvel at the many, many performance warnings that your driver may or may
not emit.
The GLEW headers of Ubuntu 12.04 LTS don't know about GL_KHR_debug yet,
so we have to test for it before using its enum. Additionally, drivers
without support for GL_KHR_debug would emit INVALID_ENUM, so we test for
driver support too.
When an error's log output is represented graphically the graphics
operation can lead to another error (or the same error again), which
will be logged graphically again and so forth, until stack overflow.
So log to the log file only.
To create debug contexts, we have to use glXCreateContextAttribsARB. To use
that, we have to initialize GLEW, which means creating a dummy GL context. To
create a dummy context with the same FB config as the final one, we need to...
initialize GLEW, because it suppresses the GLX 1.4 function declarations.
So instead we'll just manually initialize the three function pointers we're
going to need.
NativeToolsExport.cmake gets generated in non-cross builds so potential
cross builds later know where to find a native c4group.
Ignore it so in-tree builds don't accidentally commit it.
The GL driver is allowed to use different entry points depending on the
context. This means that we can't just initialize GLEW once and use it
all the time, but we must refresh the entry point list every time we
create a new context.
A multi-statement macro requires the user to wrap its invocation in
curly braces if it's used as body of a conditional or loop. This is
confusing and leads to strange errors (like in lines 550f).
