Fixes for image binding
support floating-point tiff files
support 32-bit as well as 16-bit AE displacement maps
fix some build issues on windows/ppremake
Disable error checking by default for a substantial performance increase
Revert accidental checkin of memory barrier
Add F_r32i texture format (useful for atomic image writes from shaders)
Allow Shader parameter in ShaderAttrib::make
Add support for passing int arrays and vectors to GLSL shaders.
Int shader inputs
Allow calling dispatch_compute directly to GraphicsEngine
Allow passing matrices to GLSL shaders either via NodePath or directly as a Mat4
Use explicit cast to try and squelch compile error
Fixes for OpenGL ES
