Merge r4562-4570 from trunk:
Remove wrong _IRR_OVERRIDE_'s which prevented compiling on Linux. Updated changes text file. EMT_TRANSPARENT_ALPHA_CHANNEL_REF working again like in older Irrlicht versions (1.4 or so): It uses again SMaterial::MaterialTypeParam instead of a hardcoded values and makes an exception when MaterialTypeParam is 0 (using it like 0.5 instead) to ensure it works by default. See http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=48940 for new discussion. _IRR_OVERRIDE_ needed a few more checks on gcc to prevent compile warnings on some systems. git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/branches/ogl-es@4643 dfc29bdd-3216-0410-991c-e03cc46cb475master

|
|||
- Removed VS6 .dsw / .dsp project files - VS6 is no longer supported.
|
||||
|
||||
- Added support for PVR textures. Loader offer support for compressed DXT1-5, PVRTC/PVRTC-II, ETC1/ETC2 texture formats.
|
||||
- Material renderers which offers blending feature (eg. EMT_TRANSPARENT_ALPHA_CHANNEL, EMT_ONETEXTURE_BLEND etc.) require SMaterial::BlendOperation set to other value than EBO_NONE.
|
||||
- Removed support for built-in T&L variables in ASM/GLSL shaders (variables related to vertices eg. gl_MultiTexCoord0 are still supported). This change allow us to reduce CPU overhead in shader material renderers.
|
||||
- IGUIEnvironment::hasFocus has now a parameter checkSubElements as subelements are usually seen as part of an element. Default unfortunately must be false due to backward compatibility.
|
||||
- Add IGUIElement::isTrulyVisible which works like ISceneNode::isTrulyVisible and checks for parent visibility as well.
|
||||
- Improved DDS loader and added support for DXTn (DXT1-5) compressed textures in OpenGL and Direct3D9 drivers.
