* Fixed QOpenGLFunctions feature/extension detection to check GL versionSamuel Rødal2013-02-091-2/+9
| | | | | | | | | | If the GL version is new enough the extension string won't contain features that have been standardized. So far we only check for FBOs.

| | | | | | | | | | Angle, for instance, which is now the default on Windows, does not support the GL_BGRA_EXT format as input for glTexSubImage2D(). In the case where it's not detected, we therefore need to flip the bytes in the input. Change-Id: Ibe78d0223e3c2c39cb1943cdcf67103044d00aa7 Reviewed-by: Samuel Rødal <samuel.rodal@digia.com>

* OpenGL: Use official glext.h and gl2ext.h headersSean Harmer2012-08-201-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Khronos group makes the glext.h (Desktop OpenGL) and gl2ext.h (OpenGL ES2) headers officially available nowadays. Most (all?) Linux systems ship this by default. On Windows platforms the glext.h file needs to be downloaded from http://www.opengl.org/registry/api/glext.h and placed alongside the system OpenGL header. Making use of the official header reduces the maintenance overhead for OpenGL support in Qt by removing the need to copy and paste definitions into the Qt sources. As the Khronos-provided headers are standardised and backwards and forwards compatible we can utilise these for all platforms rather than just for Windows. This means that all definitions required by Qt will be present even if the system ships out-dated equivalents. Mac OS X needs special handling in that we should always use the system-provided headers there. This is because Apple controls the OpenGL driver and the headers that go along with it. As such there is no possibility that the driver exposes additional functionality compared with the system-provided OpenGL headers. Apple has also decided to make different decisions about some OpenGL typedefs compared to other implementations. For example, Apple typdefs GLhandleARB to void* whereas other platforms use unsigned int. The alternative, which is to use the system provided glext.h (or gl2ext.h) header means that Qt code would need to check for the availability of such definitions wherever it is not guaranteed to be provided by core OpenGL/ES just to compile. The proposed approach means that Qt can compile regardless of the system's OpenGL extension support. We just need to be rigourous in runtime checking of support for extensions but that is already a requirement (and is missing in a few places, see TODO's added in this commit). The official Khronos headers are added to Qt as qopenglext.h - Desktop OpenGL qopengles2ext.h - OpenGL ES2 They need to be public but not part of QtGui module include, hence the headers have been modified by adding #if 0 #pragma qt_no_master_include #endif to them. This has been tested on: Gentoo Linux with GCC 4.6.3 Windows 7 with MSVC 2010 Mac OSX 10.8 with Apple clang 4.0 (based on LLVM 3.1svn) QNX with qcc (based on GCC 4.4) A small change is needed to QtDeclarative when building for OpenGL ES 2 after applying this commit.

* OpenGL: Add finer-grained functionality checks for NPOT texturesSean Harmer2012-08-061-2/+3
| | | | | | | | | | | | | | | | The GL_IMG_texture_npot extension only provides partial support for npot textures in that it allows use of npot textures but it does not support the GL_REPEAT texture mode (needed for tiling fill modes in the QQ2 image element). Adding this new finer-grained feature check allows QQ2 to still use npot textures where GL_REPEAT is not needed with only the IMG extension present. A follow-up commit will make a check for this in qtdeclarative. Change-Id: Iff3dbdb955fb334d9e32f3abd49e90ff0ed9836c Reviewed-by: Gunnar Sletta <gunnar.sletta@nokia.com>
