0.11.0

• Formulas now support more stencils: bilaplacian_a, trilaplacian_a, gaussian_a, sobelN_a, sobelNE_a, x_gradient_a, x_deriv2_a, x_deriv3_a, gradient_mag_squared_a (and similarly for the other chemicals and directions). Several patterns have been converted from kernel rules to formula rules as a result.
• Formulas now support x_pos, y_pos and z_pos, giving the cell location in each direction, in the range [0,1]. This allows a neater and more accurate way of implementing parameter maps.
• Formulas now support a_e, a_nw etc. in a more natural way. Instead of accessing the float4 block that is the neighbor of the current block, these keywords return a float4 that has the four values that are neighbors in the specified way. Now we can do e.g. a = a_ne; in a formula to have the whole pattern shift down and left by one pixel. This is a breaking change: formula rules that accessed cells using a_w, a_e, a_nw, a_se, etc. will no longer behave as they did before.
• New pattern setting: accuracy. Controls the size of the stencil. Use "low" to run fast, and "high" to run accurately.
• Parameter dx is now reserved for controlling the grid spacing of the Gaussian, Laplacian, bi-Laplacian and tri-Laplacian stencils. Formula rules no longer need to write e.g. laplacian_a / (delta_x * delta_x) and can just write laplacian_a since the value of dx is used in the stencil computation.
• New render setting: colormap, with 11 maps available: "HSV blend", "spectral", "spectral reversed", "inferno", "inferno reversed", "terrain", "terrain reversed", "orange-purple", "purple-orange", "brown-teal", "teal-brown". The old behavior (HSV interpolation between two colors) is still available - choose "HSV blend".
• New render setting: plot_ab_orthogonally. If true in a 1d pattern, we plot chemicals 'a' and 'b' against each other in the line graph, allowing us to show e.g. Schrodinger1926/packet.vti or Yang2006/jumping_cGL.vti in a more useful way.
• Moved View Full Kernel... and Show OpenCL Diagnostics... to the View menu.
• Mac app requires macOS 10.10 or later.
• More smaller brush sizes.
