* Add Bicubic Shader to OpenGL Backend Aaron2017-12-301-0/+1
| | | | | | | | This shader uses the equation described by R. Keys in the paper 'Cubic Convolution Interpolation for Digital Image Processing' which is, in this case, the same as a Catmull-Rom spline. This produces a sharper upscaled image than bilinear filtering. The new shader is selected by setting gl_glsl_filter to 2. Consequently, gl_glsl_filter is now treated as an int rather than a boolean. Also fixed a variable name problem in the code guarded by GLSL_SOURCE_ON_DISK.
