tigertang a02085ea98 Update StbCommon.h to stay up-to-date with stb_image.h. 
This enables C++ API users to statically link Assimp into their projects along with stb_image.

seanth 8cde65bfe8 Updated AIC table 
The previous table was in an incorrect order, leading to index references in DXF producing the wrong colours when converted.

Also added other entries to bring the total number of ACI colours up  to the number that can be used in DXF files

seanth 240fa97fed Update DXFLoader.cpp 
Changed order of operations for insert positioning and scaling. Need to position the inserts before scaling it, otherwise the position ends up up being position*scale

seanth 727001b0ca Update DXFLoader.cpp 
Edited out line suspected to be causing changes in position when changes in scale are made to inserted BLOCKS

Andre Schulz 9d71a275c3 X3D: Don't convert IndexedLineSet polylines with > 2 indices to triangles/polygons 
Currently, when the coordIndex attribute of an IndexedLineSet contains a
polyline with > 2 indices, X3DGeoHelper::coordIdx_str2faces_arr() will
incorrectly determine the primitive type to be aiPrimitiveType_TRIANGLE or
aiPrimitiveType_POLYGON instead of aiPrimitiveType_LINE.

To fix this, this commit adds functions to explicitly handle an IndexedLineSet.

Fixes #3101

Alexandre Avenel aae93691b9 Fix container overflow in MMD parser 
Using reserve, buffer size is not updated. Since data is directly inserted and not using push_pack,
this can lead to a container overflow.

Wojciech Matyjewicz 2235518b3c Fix parsing <instance_image> in <sampler2D>. 
The regression was introduced in 904f17f.

Since all the cases are now fully handled at the child level,
visiting the whole subtree is changed into iteration over the children.

julianknodt 9efbbe0a69 Read int from uvwsrc 
Previously was reading a uint, which always failed. Since the output was never checked, this
seemed to work, and works fine for most models since they only use UV channel 0.
