OpenGL ES 2 version 2.1 for Warp3D Nova / AmigaOS4 is on my FTP for testers to test now.

- added support for so called 2D rectangle textures. The most important difference compared to "normal" 2D textures is that you access it by texel-coordinates and not by normalized UVs. Use GL_TEXTURE_RECTANGLE instead of GL_TEXTURE_2D for glBindTexture. Use sampler2DRect instead of sampler2D inside your fragment-shaders.

- consequently, glGetActiveUniform can now return the uniform-type GL_SAMPLER_2D_RECT.

- consequently, glGet now supports GL_TEXTURE_BINDING_RECTANGLE.

- consequently, the library's internal patcher enables the GL_ARB_texture_rectangle extension so that the library's internal glsl-compiler swallows fragment shaders which use sampler2DRect etc.

- updated the glslangvalidator-redux command line program with that behaviour as well.

- consequently, added GL_ARB_texture_rectangle and GL_EXT_texture_rectangle to the extensions string.

- performance: lots of micro optimizations (e.g. more branch hints, etc.)

- performance: VBO multibuffering values further tuned.

- performance: DBO multibuffering.

- performance: memcopy-with-stride optimized for different element-sizes.

- performance: hash-with-stride optimized for different element-sizes.

Those optimizations gave us some significant gains here and there and especially corrected the slight losses on some games introduced with the last version, but after trying a lot I'm out of more options for now ;)
Thanks and greets to Kasie Kasovich (kas1e) for feature-requesting and testing :)
