Made geometry creation use IMesh instead of IAnimatedMesh. Moved Sphere meshbuffer into geometry creator and changed sphere scene node accordingly.

Mem leak fixed in d3d RTT code identified by vitek. Some redundant code removed and OpenGL shader materials fixed for changing number of textures.

Temporarily disabled the non-alpha textures for d3d due to lack of mipmap support. Have to fix that first.

git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@802 dfc29bdd-3216-0410-991c-e03cc46cb475

Added a new texture creation flag for specifying the desired texture format. The new flag chooses a non-alpha channel texture format. This will save some texture memory (one fourth for 32bit textures).
Fixed another COpenGL render state bug.
Fixed several color conversion methods.

fixed bugs with listbox automatic visibility of scrollbars, and clicking on listbox scrollbars when in a combo box.
items in a listbox are now selected as you type their text.

OpenGL render targets are now the same way up as in the other drivers. When setting the projection matrix of a render target, the Y axis is flipped and polygon winding is switched to counter-clockwise.

Reordered some more OpenGL render state settings in the materials.

fixed getOriginalSize in textures in Burning's renderer. Had to add a new method to get the size of the largest mipmap (getMaxSize), as the texelarea functions needed this value.
