The C++ standard library comes with perfectly fine implementations of
these functions, so there's no point in reimplementing them just for the
hell of it.
Instead of one draw call for each tile, do the whole operation with a single
draw call by setting GL_REPEAT on the texture. This affects sky, the upper
board and the background.
This also allows to remove some code that was making sure surfaces are big
enough.
As discussed in http://forum.openclonk.org/topic_show.pl?tid=2917, I
have merged all copyright notices into a single file and referenced that
merged file from each source file.
For the updated source files, the timeline has been split into three
parts:
1. Pre-RWD code (before 2001)
2. RWD code (2001 through 2009)
3. OpenClonk code (2009 and later)
All pre-RWD copyright notices have been left intact, as have RWD-era
copyright notices where the file did not have a RedWolf design copyright
notice but only individual author ones. All copyright notices of the
OpenClonk era have been replaced by a single notice ranging from the
first recorded year to the current year (2013). Mape code did not get a
OpenClonk Team copyright notice because it is somewhat separate from the
main OpenClonk codebase and has only been touched by Armin Burgmeier.
4e875f4 didn't quite catch all instances of C4BltTransfor::SetRotate
being called, and silent conversion from int to float meant that those
rotations were incorrect by a factor of 100.
Direct3D hasn't worked for more than a year now, and there don't seem to
be any efforts to revive it. Remove it and concentrate on better OpenGL
support.
This fixes the lightbulb symbol from floundering around back and forth when
zoomed in and scrolling. Since C4Facets can be used to specify a target area
to draw into (such as in C4DefGraphics::Draw), and since this area can be
zoomed, sub-pixel precision can be achieved this way in such drawing
operations.
