Updates

Recent updates

• Render to texture implemented, via EGL Pbuffers
• LINE_LOOPs now close properly in Begin/End (mrbrown)
• Fixed glTexSubImage, which was broken.
• Implemented swizzled textures, which gives some programs a large performance boost.
• Fixes for switching between two different indexed textures.
• A big chunk of under-the-hood work to bring render-to-texture a little closer, including VRAM heap compaction.
• Fixed up initialization, which was surprisingly broken. It should now work reliably on 1.0 PSPs.
• Implemented glPush/PopAttrib, and glPush/PopClientAttrib. These are not strictly part of EGL, but they're very useful.
• Added GL_PSP_view_matrix extension to make use of the PSP's view transform matrix. This adds the GL_VIEW_PSP matrix, which is selectable with glMatrixMode().
• Added automatic mipmap generation. This uses the hardware to do mipmap generation, but it only works for RGBA textures (not compressed, luminance/intensity or indexed). Includes an extension for mipmap debugging.
• Implemented gluScaleImage and gluBuild2DMipmaps
• Fixed problems with mipmaps
• SVN PSPGL updated. I will keep maintaining the Mercurial trees, but the SVN version on pspdev.org is now up to date. Check it out with svn co svn://svn.pspdev.org/psp/trunk/pspgl
• Various API additions to get ODE's demos to compile.
• Improved monochrome textures to use an internal cmap to reduce the size of the internal form of the textures (they're native now)
• Implemented PSP_vertex_blend extension
• Implemented spline patch surfaces
• Implemented indexed forms of bezier and spline patches
• Cleaned up varray code. This doesn't have any visible effect, but it does simplify the vertex array code and makes it easy to add other indexed primitvies (ie, beziers)
• Implemented glDrawBezierArrays(). Still to do: indexed arrays. Details below
• fixed spotlights; documented spot exponent and cutoff angle
• added magnifier test program for glCopyTexImage2D
• implement glCopyTexImage2D - pretty good performance
• fixed bug in native vertex format detection
• fixed bugs in glInterleavedArrays
• fixed handling of pinned buffer; removes performance problem with index buffer objects
