Bug description:
It looks like that objects allocated inside GLWindow::addShaders and
GLVertexBuffer::addUniform methods are never deleted.
I'm using a plugin (compiz-cms) that uses both those methods and it
leaks memory very fast:
==21530== 24,821,632 (10,638,048 direct, 14,183,584 indirect) bytes in
443,252 blocks are definitely lost in loss record 1,143 of 1,145
==21530== at 0x4A068F3: operator new(unsigned long) (in
/usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)
==21530== by 0x6536B2C: GLVertexBuffer::addUniform(char const*, int) (in
/usr/lib64/compiz/libopengl.so)
==21530== by 0xC351FFB: CmsWindow::glDrawTexture(GLTexture*, GLMatrix
const&, GLWindowPaintAttrib const&, unsigned int) (cms.cpp:530)
